Finding Transpose of Matrix in GAMS and solving datareconciliation problem

GAMS
1

To do matrix multiplications, transposes and inverse other package can be used, as matlab and scilab (the last one is free).
Regarding the use of Scilab, I’ve developed a framework in this tool for data reconcilation and gross error detection ( https://code.google.com/p/dr-ged-benchmarks/ ), where > you can find the implementations and behchmark test problems.
I know this is not a Scilab forum, but I’m suggesting this tool since I’ve tried to use Gams in the past and found Matlab/Scilab more helpfull.
I had some terriable experience rewrote in GAMS some reonciliation code written in matlab.
matrix multiplications utillities in GMAS does sucks … sometimes I have to unload GAMS 2D parameter into gdx file and call lapack myself.

Hello Suryanarayana

As Yan.ren said in the GAMS list, the transpose and the matrix multiplication in GAMS is pretty straightforward.
I think you won’t have dificulties in do it. If you have, send me your Gams code.
