Change rank of allocatable arrays

Change rank of allocatable arrays

Change rank of allocatable arrays


Say I have a 50x50 allocatable array and I want to change this to a 100x1 allocatable array. What is the best way to do this? I am using the reshape command but it does not work well with allocatable arrays.

This is a simple question and I suspect there is a simple solution.

My current block of code looks something like this:

do QindIC= 1, NqIC
allocate(q0p(NsFA(QindIC), NqIC))
do FAindIC= 1, NsFA(QindIC)
q0p(FAindIC, QindIC)= qfinalICT(QindIC)%qfinalICvalT(FAindIC, QindIC)
end do
q0pp= reshape(q0p, (/sum(NsFA(:)), ppnull/))
end do

This results in a "segmentation fault - invalid memory reference" error. Any help would be much appreciated.

Please let me know what you think.

Thank you,

You have a 50 X 50 ARRAY OR 2500 ELEMENTS. You are attempting to reshape them into a 100 element array. How is that going to work?

That was a bad example. Either way, I solved the problem using the pack intrinsic function.

Thanks anyway!
