Re: How to shift the columns of a PDL matrix

[lin0]

Hi Anonymous Monk,

you could use something like:

$pdl = append(zeroes(1,$pdl->getdim(1)), $pdl(0:-2,:));

where $pdl is your 8 columns by 120 rows piddle

Note: I am assuming you are using PDL::NiceSlice

Cheers,

since you don't want to grow your matrix, it is even simpler to use rotate to shift your columns and then insert your new data.

$pdl=$pdl->rotate(1); 
$pdl(0,).=$new_data # your vector.
