Hi, there

I am reading up some LDPC source codes in C I downloaded, I wanted to check
it against Matlab,
however the matrix doesn't work in Matlab, and fec.ldpcenc complains the
following,

"The last (N-K) columns of the parity-check matrix must be invertible in
GF(2)."

How do I modify the matrix? It's quite large, 128*256.

Or how do I find a new matrix for it?

TIA!
