Re: file error from write_matrix

Bryan,

I think it might be the tilde at the start of your filename. The
Unix command interpreter knows what to do with it; IIRC, in general
NCL and other languages do not. I have fallen into this trap myself
at times. ;-)

Other possibilities are misspelling in path (check carefully);
missing lower level directory; missing write permission for
directory; previous file with same name exists. HTH.
