I have IDL arrays, that I would like to write out to a text file
so that it retains the dimensionality in the form of rows and columns.
For example, if I have an array test(360,180), I would like to write it out
to a text file with 360 columns and 180 rows.
Anyone have any better suggestions than the solution I am using below:
openw,1,'output_file'
printf,1,test,format=`(360f6.2)'
close,1
I have found programs in IDL on the net that read column formatted files,
but havent found any that write out to columns.
I would appreciate any tips.
Thanks,
Mila Mitra

Hi Mila,
the way you suggest is right. for more flexibility try
columns=n_elements(data(*,0))
format_string= '(' + strtrim(string(columns),2) + 'f9.4)'
openw,/get_lun,file_unit,out_file
printf,file_unit,data,format=format_string
free_lun,file_unit
There are possibly more ways to do it, but this is straight forward and
no effort.
Have a nice time
