prefield - prepare input file for 'muplot' to plot 2-d fields by arrows
prefield <file> <scale> x y F_x F_y
prefield will prepare input file for 'muplot' to plot 2-d fields by arrows
Example:
On running "prefield test.dat 20 1 2 5 6" the source file 'test.dat' will be read, and a field-data file will be produced with the 1st and 2nd columns being the x and y space-positions like in the source file, whereas the fields F_x and F_y are calculated from the values in the 5th and 6th columns of the source data multiplied by the second command line option, which means in this example a 20-fold magnification.
Use '-' as file name to read from <stdin> and write to <stdout>.
