Splines

knots(d,N,μ,a,b)

Compute the knot sequence of degree d, of multiplicity μ with N equally spaced subintervals between a and b.

The default values are μ=1, a=1.0, b=1.0.

Bspline curve with a matrix dxm of control points points and a basis .

Bspline surface with a tensor dxm1xm2 of control points points and bases basis1, basis2 .

Bspline volume with a tensor dxm1xm2xm3 of control points points and bases basis1, basis2, basis3.
