I am running a fit using a custom function. Naturally, after the pepper invocation in the custom function I use a rescale command to rescale the calculated with the experimental y-values.

[x,y] = pepper(fullSys,Exp,Opt);
y_ref = Sys.spc;
y_rescale = rescale(y(:), y_ref(:), 'lsq0');

On a Linux machine running Matlab 2018a it works just fine. On a Windows machine running Matlab 2019a I get the error:

Error using esfit
Error using rescale>preprocessInputs (line 112)
Interval bound arguments must be real and numeric.

Error in esfit_simplex

Error in esfit

Error while evaluating UIControl Callback.

As there is also a Matlab rescale function (https://fr.mathworks.com/help/matlab/ref/rescale.html) I can't tell where the error comes from. I suppose the ES rescale function overrides the Matlab one?

Is there a way to debug this?

Thanks!

In the development version this has been fixed, the ES function rescale was renamed rescaledata which avoids, as in your case, the other Matlab rescale function.

Yes that did the trick!

Thank you Matt.
