How to exclude a variable from fit by custom function.

Hello,

I have a custom function y= a+g/(exp(T/x)-1) where T is a constant which has been already calculated.

I want to fit my data set by using a and g only. How to state that T is already predefinded and should be excluded from the fitting?

Try this:

T = 42;                                             % Defined In Your Workspace
y = @(a,g,x) a+g./(exp(T./x)-1);

To use it with other toolboxes:

y = @(b,x) b(1)+b(2)./(exp(T./x)-1);
