Problem while reading multiple images from a file

Hello everyone!

I am trying to read some images from a file and have written this code:

outLoopValues = [1.5, 2.0, 2.5] % Whatever values you want.
for m = 1 : length(outLoopValues)
	index = outLoopValues(m);


I = imread('Im - %.1fcm.png', m);
f1=figure;
imshow(I)
targetSize = [960 960];
r = centerCropWindow2d(size(I),targetSize);
J = imcrop(I,r);
end

but i get this error:

Error using imread>get_full_filename (line 567)
File "Im - %.1fcm.png" does not exist.

The problem seems to be that the values that are paased to m in the for loop are not 1.5 etc but 1.500 so when it tries to find my image which is named Im - 1.5cm it cant because m is 1.500 and not 1.5

Do you know how to fix this?

I = imread(sprintf('Im - %.1fcm.png', m));

Thanks for your answer @David Hill but i get an error when i try to use it :

Error using imread>parse_inputs (line 501)
The file name or URL argument must be a character vector or string scalar.

Error in imread (line 339)
[source, fmt_s, extraArgs, was_cached_fmt_used] = parse_inputs(cached_fmt, varargin{:});

Sorry, should be sprintf
