I need to resolve an undeterminated matrix that corresponds to an Flux balance Analysis applied on Glicolysis pathway, I have 19 metabolites in the rows, and 40 fluxes in the columns. I want to know about its null space, rank, and space dimensions... Some programs? or any methods? Some ideas?
How can I resolve a matrix of 13 rows and 40 columns?

0There is also Octave, which is free, and should certainly be able to handle a $19 \times 40$ system of equations. – 2012-05-24

You need to be a little more specific about what you want to achieve but here's something you could get started with:
Fire up Octave. Relevant Functions:
a = rand(19,40) %Just to get a random matrix to work with. null(a) %Null space rank(a) %Rank rref(a) %Row Reduced Echelon Form
Anything else you need?
