homogeneous linear system in simulink
|

| Hello.
I have an homogeneous undercostrained system, and I'd like to solve it
via simulink, preferably with the SVD decomposition. The problem is that
the SVD solver under the signal processing blockest (as all teh other
solver) gets me the [0...0] as the solution of the system. But I want a
non null solution.
Is there any way I can get that from simulink?
Or maybe via s-function it is possible to do so (i.e. are there any C
libraries in matlab that can handle matrices and linear systems?)
Thank you
Andrea

| Hi Andrea, first you need have in acount that the matrix need to have
the same size, second, if you homogeneous linear system have
restrinas conditions, you can also have the solution with
functions.....bye
