1、mat lab中如何读取文本文件今天需要做个matlab读取txt文件,在网上收集了下,查到了几篇不错的,总结一下,方 便大家(包括me)使用:下面这个函数是取filein中的第line行写入fileout中的程序,如果想实现取特定几行, 只要稍微修改一下就可以。function dataout-dataread(filein,fileout,line)fidin=fopen(filein,...
Example 2: Using STRREAD to read the words in a line % This command uses the cell array created in Example 1 to % read in each word of line 28 in 'file' to a cell array, words words = strread(file{28},'%s','delimiter','') CODE: Example 3: Using TEXTREAD to read in text an...

3.xlsread A = xlsread('data.xlsx','Sheet1'); 1 用法较为简单不过多赘述。load,csvread类似。dlmread的用法也较为简单 A=dlmread('lcode.dat','delimeter') 1 textscan 使用textscan之前必须要先fopen文件,基本使用示例为 fid = fopen('filename.txt'); ...

text = fileread(filename) 以字符向量形式返回文件 filename 的内容。 filename参数是要读取的文本文件的名称(注意:低版本MATLAB中请使用字符向量指定文件名,使用字符串类型会报错)。根据文件所在的位置,我们通常会遇到以下两种情况: (1)文件存在于当前文件夹或搜索路径上的某个文件夹中(忘记搜索路径的同学可以看第...
