How can i change variable name by code???

Hello sir..

I faced a awesome problem

in my code

ext = '*.txt';
files = dir(strcat(pathDir,slash,ext));

for i=1:length(files)
B = rand(63);
C = files(i).name
???? 
end

in a loop, i want to rename variable B to C

How can i do that??

"I faced a awesome problem"

Which is easily solved using much better** indexing, just as the documentation shows:

https://www.mathworks.com/help/matlab/import_export/process-a-sequence-of-files.html

** better in the sense simpler, neater, much more efficient, less buggy, and easier to debug than what you are attempting.

"i want to rename variable B to C"

Consider what will happen if the file is named "1+2", or "quit" or anything that is not a valid variable name, e.g. anything ending with file-extension .txt (like your example).

Why do you want to force yourself into writing complex, obfuscated, buggy code?

rename variable B to C:

C = B;

I'm afraid you want top do something else: Creating a variable with a dynamically determined name. This is a bad programming practize. Don't do it, because you drill a whole inyour own knee. See TUTORIAL: Why and how to avoid Eval
