I have a data file in which each row has a variable number of columns. I am
reading this file into a regular Perl array first in order to do some basic
pre-processing of the data. I then am presently adding 0s to pad each row to be
as long as the longest row and so I have a rectangular array. I then pass the
array to pdl() and things seem OK.
Is there a way to do this easier though? To skip writing my own loop to pad the
array first? That is, a way to take the irregularity shaped array and have pdl
make it rectangular for me?
