Trisol: Trisol

In geocryology/PermafrostTools: PermafrostTools

Description

Solves tri-diagonal matrix equations.

Usage

Trisol(a, b, c, d)

Arguments

a	Lower diagonal term [Z], Note: a[,0] is zero
b	Center diagonal term [Z]
c	Upper diagonal term [Z], Note: c[.Z-1] is zero
d	Right-hand side (on input) / solution (on output) [Z]

Details

Solves matrix with Thomas algorithm, Z discretizations with depth.

Value

Solution vector result. In case of heat conduction this is the temperature for the new time step.
