Tri-diagonal Matrix Algorithm (TDMA)

Is there anybody who has coded the Tri-Diagonal Matrix Algorithm (TDMA or Thomas algorithm) in mathcad and would be willing to share it?

Dear Festivus, I had seen your message today for the first time since

I am migrating to Mathcad Prime 7.0. Attached is the TDMA that I had

developed in 1985 (The Fortran source code which I had used as

basis is my TDMA and it states the date). 

 

I have successfully used TDMA in two distinct heat transfer simulations

in a transient interior ballistics solution of a RLPG (Regenerative Liquid

Propulsion Gun and also in a steady state thermal liner heat transfer in

F100 thermal liner.

 

It is my pleasure to freely share my IR&D (Independent Research

and Development) algorithms.

 

Attached are the "Algorithm derivation along with the Fortran solution

implementation" in one PDF file. The second file is my implementation

of TDMA imported into Mathcad Prime v7.0 from the Mathcad v15 original

file.

 

I hope that these TDMA files will serve well our PTC Community.

 

Sincerely

 

Julio C. Banks
