How to save the command history in a text file in MATLAB

Question

I want to save the value of a variable from MATLAB command history in a text. I am trying the command:

Save([d:/work/abc.txt], 'z1', '-ASCII');

An error appears

Error: input charecter is not valid in MATLAB environment or expression.

Answer 1

You should use save (with lower case for "s").

Also the filename should be defined as a string: enclose it withi two '; also you do not need the [] unless, for example, you want to build a string using a variable and / or any function to create part of the filename (eg

['d:/work/abc_' num2str(k) '.txt']

assuming k value is 3 ) to get d:/work/abc_3.txt

Try change your code to:

save(['d:/work/abc.txt'], 'z1', '-ASCII');

Hope this helps.

您所缺少的是括号内用于表示字符串的引号。

['string']
