matlab读取exceloffice的表格文件也就是xls文件本质上就是一个二维矩阵，二维矩阵是用来保存数据的最佳方式，所以在日常工作中，我们从其它地方获取的数据通常都被保存为xls格式，但处理数据时，我们却需要把xls文件的数据导入到matlab里进行处理。

如果你只处理一个文件并且只做一次的话，你可以手动来拷贝粘贴，这花费不了你太多时间。

如果有很多xls文件，或者你的xls文件的内容可能随时被修改，那么下面的方法可以派上用场。

matlab自身提供了大量的函数，包括读取office文件。

其中xlsread和xlswrite就是专门用来读取xls文件里的数据的。

这两个函数的使用方法可以直接查看matlab自带的帮助。

xlsread对于纯数据的xls文件支持很完美，也就是说当xls文件里的每个格子都是“数”时，xlsread会直接返回一个实数矩阵。

但是通常我们拿到xls文件并不是这样，它的表头多半是描述性文字，它的数据也有可能是文字，有些位置的数据还有可能是缺失的。

xlsread 对这样的文件读取无能为力，或者说需要大量的时间去协调数据的位置信息。

要是有一个函数，能够按照原有的顺序直接读取所有的单位格数据就好了。

当然，这时候返回的矩阵就不能是一个数值矩阵了，它将会是一个cell矩阵，里面的每个元素类型可能不一样。

matlab本身并不提供这个功能，但是另外有一个函数officedoc完美的实现这个功能。

这个函数包可以去OfficeDoc官方网站上去下载，解压缩后放到工作路径上即可。

使用方法可以查询help officedoc。

officedoc是收费函数包，但有免费版本，而且其免费版本可以实现上面我们所说的效果（收费版本主要是可以用来修改office文件）。

例子：在matlab中读取xls格式的文件内容如应用如下函数:1.bb=xlsread('c:feature.xls','a0:an40'),其中:c:feature.xls为文件存放的地址,a0:a40为将要读取的单元格的范围.bb为读取的矩阵在MATLAB中的变量名.2.使用m文件脚本如下:Excel = actxserver('Excel.Application');set(Excel, 'Visible', 1);Workbooks = Excel.Workbooks;Workbook = invoke(Workbooks, 'Open', [cd,'\feature\ABC.xls']);%% 读取ABC.xls:sheet1 a1(即R1C1)~an40(即R240c40) 范围内的 40by40 矩阵read_excel=ddeinit('excel','ABC.xls:sheet1');feature1 = ddereq(read_excel, 'R1c1:R40c40');feature1%% 关闭ABC.xlsinvoke(Excel, 'Quit');delete(Excel);注意:在使用时将m文件与xls文件存于同一个目录下.另外:sheet1:可以重命名,且读取sheet的名称要和实际存放的名称相同.matlab读取excel,txt文件函数注意matlab不识别中文，读写的文件中最好不含有中文excel读取函数xlsreadtext 读取函数csvreadXLSREAD Get data and text from a spreadsheet in an Excel workbook.[NUMERIC,TXT,RAW]=XLSREAD(FILE) reads the data specified in the Excelfile, FILE. The numeric cells in FILE are returned in NUMERIC, the textcells in FILE are returned in TXT, while the raw, unprocessed cellcontent is returned in RAW.[NUMERIC,TXT,RAW]=XLSREAD(FILE,SHEET,RANGE) reads the data specifiedin RANGE from the worksheet SHEET, in the Excel file specified in FILE.It is possible to select the range of data interactively (see Examplesbelow). Please note that the full functionality of XLSREAD depends onthe ability to start Excel as a COM server from MATLAB.[NUMERIC,TXT,RAW]=XLSREAD(FILE,SHEET,RANGE,'basic') reads an XLS file asabove, using basic input mode. This is the mode used on UNIX platformsas well as on Windows when Excel is not available as a COM server.In this mode, XLSREAD does not use Excel as a COM server, which limitsimport ability. Without Excel as a COM server, RANGE will be ignoredand, consequently, the whole active range of a sheet will be imported.Also, in basic mode, SHEET is case-sensitive and must be a string.[NUMERIC,TXT,RAW]=XLSREAD(FILE,SHEET,RANGE,'',CUSTOMFUN)[NUMERIC,TXT,RAW,CUSTOMOUTPUT]=XLSREAD(FILE,SHEET,RANGE,'',CUSTOMFUN) When the Excel COM server is used, allows passing in a handle to acustom function. This function will be called just before retrievingthe actual data from Excel. It must take an Excel Range object (e.g. oftype 'Interface.Microsoft_Excel_5.0_Object_Library.Range') as input,and return one as output. Optionally, this custom function may returna second output argument, which will be returned from XLSREAD as thefourth output argument, CUSTOMOUTPUT. For details of what is possibleusing the EXCEL COM interface, please refer to Microsoft documentation.INPUT PARAMETERS:FILE: string defining the file to read from. Default directory is pwd.Default extension is 'xls'.SHEET: string defining worksheet name in workbook FILE.double scalar defining worksheet index in workbook FILE. SeeNOTE 1.RANGE: string defining the data range in a worksheet. See NOTE 2.MODE: string enforcing basic import mode. Valid value = 'basic'. Thisis the mode always used when COM is not available (e.g. on Unix).RETURN PARAMETERS:NUMERIC = n x m array of type double.TXT = r x s cell string array containing text cells in RANGE.RAW = v x w cell array containing unprocessed numeric and text data.Both NUMERIC and TXT are subsets of RAW.EXAMPLES:1. Default operation:NUMERIC = xlsread(FILE);[NUMERIC,TXT]=xlsread(FILE);[NUMERIC,TXT,RAW]=xlsread(FILE);2. Get data from the default region:NUMERIC = xlsread('c:\matlab\work\myspreadsheet')3. Get data from the used area in a sheet other than the first sheet:NUMERIC = xlsread('c:\matlab\work\myspreadsheet','sheet2')4. Get data from a named sheet:NUMERIC = xlsread('c:\matlab\work\myspreadsheet','NBData')5. Get data from a specified region in a sheet other than the firstsheet:NUMERIC = xlsread('c:\matlab\work\myspreadsheet','sheet2','a2:j5')6. Get data from a specified region in a named sheet:NUMERIC = xlsread('c:\matlab\work\myspreadsheet','NBData','a2:j5')7. Get data from a region in a sheet specified by index:NUMERIC = xlsread('c:\matlab\work\myspreadsheet',2,'a2:j5')8. Interactive region selection:NUMERIC = xlsread('c:\matlab\work\myspreadsheet',-1);You have to select the active region and the active sheet in theEXCEL window that will come into focus. Click OK in the DataSelection Dialog when you have finished selecting the active region.9. Using the custom function:[NUMERIC,TXT,RAW,CUSTOMOUTPUT] = xlsread('equity.xls', ..., @MyCustomFun) Where the CustomFun is defined as:function [DataRange, customOutput] = MyCustomFun(DataRange)DataRange.NumberFormat = 'Date';customOutput = 'Anything I want';This will convert to dates all cells where that is possible.NOTE 1: The first worksheet of the workbook is the default sheet. If SHEET is -1, Excel comes to the foreground to enable interactiveselection (optional). In interactive mode, a dialogue will promptyou to click the OK button in that dialogue to continue in MATLAB.(Only supported when Excel COM server is available.)NOTE 2: The regular form is: 'D2:F3' to select rectangular region D2:F3 in a worksheet. RANGE is not case sensitive and uses Excel A1notation (see Excel Help). (Only supported when Excel COM serveris available.)NOTE 3: Excel formats other than the default can also be read.(Only supported when Excel COM server is available.)See also xlswrite, csvread, csvwrite, dlmread, dlmwrite, textscan.Reference page in Help browserdoc xlsreadCSVREAD Reada comma separated value file.M = CSVREAD('FILENAME') reads a comma separated value formatted file FILENAME. The result is returned in M. The file can only containnumeric values.M = CSVREAD('FILENAME',R,C) reads data from the comma separated value formatted file starting at row R and column C. R and C are zero-based so that R=0 and C=0 specifies the first value in the file.M = CSVREAD('FILENAME',R,C,RNG) reads only the range specifiedby RNG = [R1 C1 R2 C2] where (R1,C1) is the upper-left corner ofthe data to be read and (R2,C2) is the lower-right corner. RNGcan also be specified using spreadsheet notation as in RNG = 'A1..B7'.CSVREAD fills empty delimited fields with zero. Data files wherethe lines end with a comma will produce a result with an extra lastcolumn filled with zeros.See also csvwrite, dlmread, dlmwrite, load, fileformats, textscan.Reference page in Help browserdoc csvreadMatlab如何读取Excel 表格数据Subject:Are there any examples that show how to use the ActiveX automation interface to connect MATLAB to Excel?Problem DescriptionI am trying to control Excel from MATLAB using ActiveX. Are there any examples that show how to use the ActiveX automation interface from Excel to do this?Solution:Most of the functionality that you get from ActiveX is dependent on the object model, which the external application implements. Consequently, we are usually unable tp provide much information about the functions that you need to use in the remote application to perform a particular function. We do, however, have an example that shows how to do perform common functions in Excel.We also recommend that you become more familiar with the Excel object model in order to better use Excel's ActiveX automation interface from MATLAB. You can find more information on this interface by selecting the "Microsoft Excel Visual Basic Reference" topic in the Microsoft Excel Help Topic dialog. This topic area contains a searchable description of Excel methods and properties.The following example demonstrates how to insert MATLAB data into Excel. It also shows how to extract some data from Excel into MATLAB.
