How to deal with this

Hi,

I have a large matrix that is generated in a simulation.

I have noticed that some of the columns are NAN (entire column).

Is there a way to

1) get the number of columns with NAN

2) delete the columns with NAN values

Thanks

find( any(isnan(YourMatrix)) )

and

YourMatrix(:, any(isnan(YourMatrix))) = [];
