[Scilab-users] Using Scinetcdf module

[Harpreet Singh Rathore]

Hey

You have not created the variable in the file. First you have to create a
variable in the following file using the command nccreate(filename,
'Hilb_Hy', 'Dimensions', list('r', no_row, 'c', no_column); after that you
can pass the ncwrite command and you have to pass like this ncwrite(filename,
'Hilb_Hy',Hy) as Hy is a matrix.
