I apologise. I omitted an essential part of the first unpack template (the repeat *). Please try substituting this:

my @matrix = map[ unpack 'C*', $_ ], unpack '(a' . NCOLS . ')*', $buff +er;
The template has become: '(a3954)*' which tells unpack to split the buffer into as many 3954-byte chunks as are available.

In the absence of evidence, opinion is indistinguishable from prejudice.
