Example 1: Using TEXTREAD to read in an entire file into a cell array % This command reads in the file fft.m into the cell array, file file = textread('fft.m','%s','delimiter','\n','whitespace',''); CODE: Example 2: Using STRREAD to read the words in a line % This command...
file = textread('fft.m','%s','delimiter','\n','whitespace',''); CODE: 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...

If you want to read the data line by line use fid = fopen(filename); s = dir(filename); fileSize = s.bytes; recordSize = 13; noOfREcords = (fileSize-500)/recordSize; fseek(fid, 500,"bof");% skip header of 500 bytes
上面文件首行以function开头的称为函数声明行(function declaration line),紧接一行注释称为H1行(用作lookfor指令),H1行及之后的连续注释称为在线帮助文本(help text,用作help指令),再之后的注释称为编写和修改记录(上面例子中没有,用作软件归档管理),之后是函数体。当然,除函数声明和函数体外其他都是可选的。
