Suppose that a dipole magnet survey has just been completed and tied to an absolute NMR calibration at some point. This calibration requires the entire field measured to be scaled up by a factor of 1.0157. The field was measured over a 10 × 20 point grid and written into a file containing twenty lines, each line with ten numbers in 10F8.4 format. Only three commands are needed:
READ\MATRIX\FORMAT FIELD.DAT (10F8.4) B 10 20 ! read the data into matrix B B2 = 1.0157*B ! scale the data WRITE\MATRIX\FORMAT FIELD2.DAT (10F8.4) B2 ! write to a file
