Independent variable of cfit, sfit, or
fittype object
indep = indepnames(fun)
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 character vectors, and for surfaces indep is a 2-by-1
cell array of character vectors.
f1 = fittype('a*x^2+b*exp(n*x)');
indep1 = indepnames(f1)
indep1 =
'x'
f2 = fittype('a*x^2+b*exp(n*x)','independent','n');
indep2 = indepnames(f2)
indep2 =
'n'
