This MATLAB function reads data from the first worksheet in the Microsoft Excel
    spreadsheet file named filename and returns the numeric data in array num.

    num = xlsread(filename)
    num = xlsread(filename,sheet)
    num = xlsread(filename,xlRange)
    num = xlsread(filename,sheet,xlRange)
    num = xlsread(filename,sheet,xlRange,'basic')
    [num,txt,raw] = xlsread(___)
    ___ = xlsread(filename,-1)
    [num,txt,raw,custom] = xlsread(filename,sheet,xlRange,'',functionHandle)

xlsread语句的不同输出格式，[Numeric,Txt]=xlsread('d:\\mfile\data')是读取d盘下mfile目录里的data文件。并将data文件中的数据输出为Numeric变量；将data文件中的名称输出为txt的元胞元素。

我没有编程基础，大概看看

太谢谢了。
