Evaluate Monomial Basis
Computes the values of the powers of argument t.
monomial(evalarg, exponents=1, nderiv=0, argtrans=c(0,1))
evalarg |
a vector of argument values. |
exponents |
a vector of nonnegative integer values specifying the powers to be computed. |
nderiv |
a nonnegative integer specifying the order of derivative to be evaluated. |
argtrans |
Linearly transform an argument before constructing a basis. The first element is the shift in value and the second the scale factor. |
a matrix of values of basis functions. Rows correspond to argument values and columns to basis functions.
