vbmm2

From VoxBoWiki

vbmm2 carries out various matrix operations at the command line, on VoxBo matrix files only. It also allows you to do most of these operations in parts. It's mostly for internal use in VoxBo GLM job sequences. Here's the help text:

VoxBo vbmm2 (v1.8.5pre8/May  6 2010)
| vbmm does various bits of matrix arithmetic with MAT1 files.
| below, in and out refer to the input and output matrices.  c1 and c2
| refer to the start and end columns to be produced (for parallelization).
| usage:
