No, there is ascii matrix and binary matrix.
Where "binary matrix" has a very special meaning as it indicates
a specific binary file format.
Ascii matrix, however, is more what you'd expect, stating simply
that the data is in a x/y grid, i.e. matrix form.

This is an extremely useful format for plotting images where the
height is coded as color.

e.g.

plot "-" matrix with image
1 0 0
0 1 0
0 0 1
