hi all,
I have an array 3x258, is there any way to create two different arrays where the first one will contain the columns that their last element is negative, and the other one the rest of them? thanks!

idx = myArray( end, : ) < 0;
negLastElementCols = myArray( :, idx );
theRest = myArray( :, ~idx );
