I am using the PDL module to perform statistical analysis on some basic datasets that I have.
I am having trouble figuring out how to do a simple operation (I think). I want to extract the minimum value of each COLUMN of data in a 2-dimensional PDL structure.
Here is a code fragment that I tried but didn't work:
for(my $k=0; $k<$maxColumns; $k++) {
print "Min: " . min($dataA->slice('$k,:')) . "\n\n";
print "Max: " . max($dataB->slice('$k,:')) . "\n\n";
}
The variable "$k" can't be interpreted within the slice() method.
Is there a way to perform a set operation to just get the results I want without a FOR loop?
Any help is appreciated.
Thanks.
