Hi all,

I need to create a matrix of 2 dimensions in IDL and to save in
file .sav
I know that in IDL command line is: mat=dblarr(2, 4) ....that's
correct?

But in the interface graph i don't really know....i did so:

PRO cria_mat

mat=dblarr(2, 2)

OpenR, lun, 'C:\Documents and Settings\Projeto_Estudo\mat.sav', /
Get_lun
mat = dblarr(file_lines('C:\Documents and Settings\Projeto_Estudo
\mat.sav'))
ReadF, lun, mat
close, lun


writeu, unit, mat
print, mat
help, mat
close, unit

END

Can you help me, please?
