[gradsusr] gradsusr Digest, Vol 121, Issue 6

[Jan Ising]

Hello Jeff,
    Thank you for your response however, I believe there was some
confusion. Let me explain with more detail. I am trying to calculate the
Bulk Richardson Number (my data file (a .ctl file) does not have this
predefined), to do so I need to calculate each individual component of the
BRN from the different variables in my file (MUCAPE, Wind, etc...)
separately for each gridpoint, since GrADS does not allow for 2D arrays
that the user makes (say for instance in a script). This all works fine and
the values are outputted to my .txt. file, but only as 1 column with x rows
(where x is the number of grid points there are in my file). But I need it
to be in rows AND columns so that I can use the new grid, made only of
numbers (i.e the text file) and continue working with it in MATLAB (say for
example plotting it). Sorry if this was unclear before, I tried to simplify
it so my question is better understood, but it seems I may have
achieved the opposite.
