numcoeffs

Number of coefficients of cfit, sfit, or fittype object

Syntax

ncoeffs = numcoeffs(fun)


Description

ncoeffs = numcoeffs(fun) returns the number of coefficients ncoeffs of the cfit, sfit, or fittype object fun.

Examples

f = fittype('a*x^2+b*exp(n*x)');
ncoeffs = numcoeffs(f)
ncoeffs =
     3
coeffs = coeffnames(f)
coeffs = 
    'a'
    'b'
    'n'
