B-form
The tensor-product idea is very simple. If
is a function
of
, and
is a function of
, then their tensor-product
is a function
of
and
, i.e., a bivariate function. More
generally, with
and
knot sequences and
a corresponding
coefficient array, we obtain a bivariate spline as
The B-form of this spline comprises the cell array
of its knot
sequences, the coefficient array
, the numbers
vector
, and the orders
vector
. The command
sp = spmak(
);
constructs this form. Further, fnplt, fnval, fnder, fndir, fnrfn,
and fn2fm can be used to plot, evaluate, differentiate
and integrate, refine, and convert this form.
