poiasma - Boundary point matrix contributions for fast solvers of Poisson's equation
Syntax
K=poiasma(n1,n2,h1,h2)
K=poiasma(n1,n2)
K=poiasma(n)
Description
K=poiasma(n1,n2,h1,h2) assembles
the contributions to the stiffness matrix from boundary points. n1 and n2 are
the numbers of points in the first and second directions, and h1 and h2 are
the mesh spacings. K is a sparse n1*n2-by-n1*n2 matrix.
The point numbering is the canonical numbering for a rectangular mesh.
K=poiasma(n1,n2) uses h1=h2.
K=poiasma(n) uses n1=n2=n.
