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,
\[A*x[.,i] = b[.,i]\]
