My code is a lot more complicated, so I'll show just a simplification:
a=0;
while a<4
a=a+1;
disp(['Number=' num2srt(a)])
end
This error message appears: "Undefined function 'num2srt' for input arguments of type 'double'."
I want to convert the number a to string format to display in every cycle, but I can't see where the problem is, especially because I've used num2str with doubles as inputs before, and it didn't gave any error

You used the function name num2srt but the real function name is num2str
