插入一个文本文件的内容到一个变量

Question

我想加载一个文本文件丝毫ASCII字符，把所有的内容到MATLAB一个varialbe，这是代码我想：

f =fopen('tp.txt') 

结果我得到的是1，那么它每次执行此代码行时都会增加。

然而，当我尝试：

f =load('tp.txt') 

我得到这个错误：

??? Error using ==> load 
Number of columns on line 1 of ASCII file D:\Cours\TP\tp.txt 
must be the same as previous lines. 

Error in ==> TPTI at 3 
f =load('tp.txt') 

我的目标是计算每个charachter然后计算propabilites和熵的次数。

有什么想法？

试试这个：

%// Import file contents as a string 
str = importdata('tp.txt'); %// each line is a cell 
str = [str{:}]; %// concat all lines into a single string 

%// Remove spaces. Maybe you want to remove other characters as well: punctuation... 
str = regexprep(str, '\s', ''); 

%// Count frequency of each character: 
freq = histc(double(str), 0:255); %// convert characters to ASCII codes and count
