evaluate
Value of nonlinearity estimator at given input
Syntax
value = evaluate(nl,x)
Arguments
-
nl -
Nonlinearity estimator object.
-
x -
Value at which to evaluate the nonlinearity.
If
nlis a single nonlinearity estimator, thenxis a1-by-nxrow vector or annv-by-nxmatrix, wherenxis the dimension of the regression vector input tonl(size(nl)) andnvis the number of points wherenlis evaluated.If
nlis an array ofnynonlinearity estimators, thenxis a1-by-nycell array ofnv-by-nxmatrices.
