This may be a bit out of topic. I have a matrix of ones and zeros with
which I would like to produce a picture in such a way that the ones
would be represented in black, say, and the zeros in yellow. Does
somebody know of a program (for Linux) to create my picture?
what kind of matrix?
An example follows:
x\y 0.1 0.2 0.3
0.1 1 0 1
0.2 0 1 1
0.3 1 1 0
but my matrix is much larger, i.e., with many more rows and columns.
hope, this helps
