bandsolpd#
Purpose#
Solves the system of equations \(Ax = b\) for x, where A is a positive definite banded matrix.
Format#
- x = bandsolpd(b, A)#
- Parameters:
b (KxM matrix)
A (KxN compact form matrix)
- Returns:
x (KxM matrix)
Remarks#
A is a positive definite banded matrix in compact form. See band() for a
description of the format of A.
b can have more than one column. If so, \(Ax = b\) is solved for each column. That is,
\[A*x[.,i] = b[.,i]\]
