Hello everybodey,

I'm trying to define a variable name that depends on the value i in the loop for. That's my code:

for i = 1:2:40
Magnet_H_'num2str(i)' = readimage(Bilder,i);
figure;
imshow (Magnet_H_num2str(i))
end

How I can do it?

"I'm trying to define a variable name that depends on the value i in the loop for."

Dynamically defining or accessing variable names is one way that beginners force themselves into writing slow, complex, obfuscated code that is hard to debug. Read this to know why:

Indexing is neat, simple, easy to debug, and very efficient (unlike what you are trying to do). Indexing is what experienced MATLAB users use, and you should too.
