trying to save a matrix

[vibhava]

hi,
i wish to save a 250rows x 2557columns matrix that i am getting at the end of my program to a .csv file.
e.g. I get a file xyz(250,2557) but when i am trying to write it in a .csv file using "write" statement all the columns are being written one below the other (instead of being written in 250 different columns)

can anyone tell me how can i achieve this.

thanks

Note that in Fortran the 2nd index changes fastest so you might want to redeclare your array as xyz(2557,250). If you don't do that then you'd have to write it as

integer, parameter:: rowmax=2557, colmax=250

do irow = 1, rowmax
   write (20, 100) (xyz(icol,irow), icol = 1, colmax)
enddo
100 format (1X,250(F5.2,','))

If you swap the rows and columns then it becomes

write (20, 100) xyz

Note that some output devices will automatically give you a carriage return after a specified number of characters.
