size() returns a vector with at least two elements. Historically, the colon operator ignored everything except the first element of its inputs, but as of R2025a (I think it was) the colon operator starts erroring when given non-scalar inputs.

The code needs to be changed to

for i = 1:size(relarray,1)

for compatibility with previous use.

It would not surprise me if relarray could end up being a row vector though, so potentially length(relarray) might be better than size(relarray,1), perhaps.

I tried to fix that but when I try to print this happens, should I switch to a lower version?

There does not appear to be any function named print in the COBRA Toolbox. https://opencobra.github.io/cobratoolbox/stable/modules/index.html

As a result, you are invoking the MATLAB print function which is intended to output graphics objects.
