Description

indep = indepnames(fun) returns the independent variable name or names (indep) of the cfit, sfit, or fittype object fun. For curves indep is a 1-by-1 cell array of strings, and for surfaces indep is a 2-by-1 cell array of strings.

Examples

f1 = fittype('a*x^2+b*exp(n*x)');
indep1 = indepnames(f1)
indep1 = 
    'x'
