我想加载文本文件,使用ASCII字符,并将所有内容放入MATLAB中的varialbe中,这是我试过的代码:
f =fopen('tp.txt')
我得到的结果是1,然后每次执行此代码行时它都会递增。
然而,当我尝试:
f =load('tp.txt')
我收到此错误:
??? 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的出现次数,然后计算可能性和熵。
有什么想法吗?

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
