Function Named with String Substitution

I am creating individual interpolating functions for each of 10 sets (matrixes) of x,y,z,v data, and would like to name each function based on the index 'j' of the 'for' loop in which they are created. The desired result is a set of functions named F1,F2,F3,...,F10.

Is there a way in MatLab to use string substitution in the name creation of each function?

%--------------------------------------

for j=1:10

...

F%j% = griddedInterpolant(v%j%,'spline')

...

end

Can you do this? Yes.

Should you do this? The general consensus is no. See that Answers post for an explanation and alternatives.

Thanks for the link. I was looking for an expedient method. An array of functions F(1),F(2),F(3).... would also meet my needs and be better practice . I'll investigate this route.

Yes, but only if you want to force yourself into writing slow, complex, inefficient, obfuscated, buggy code that is hard to debug. It is an approach best avoided, and almost never required.

The simple and very efficient MATLAB approach is to use indexing. You should use indexing:

N = 10;
C = cell(1,N);
for k = 1:N
    ...
    C{k} = griddedInterpolant(..,'spline');
    ...
end

Indexing is one of the very important basic concepts that is explained in the introductory tutorials:

You can use indexing with all array types: numeric, char, logical, cell, struct, table, ...

Perfect! This is the effect I wanted to achieve. I wasn't familiar with the cell function. Thank you for enlightening me to this indexing approach in MatLab.
