Description

The function x2fx.m contains a variable shadowing issue where the loop variable idx is reused in nested loops.

Affected Code Section:

for idx = 1:r          % Outer loop line 184
    ...
    for idx = 1:length(collist)  % Inner loop (overwrites outer `idx`)
        ...
    end
end

Expected Behavior

• Outer and inner loops should use different index variables.

I don't know if the same name of the inner and outer loop indexes of the programming language code will have an effect, but I recommend changing it.
