Specify $f(x)$ and $x$ interval as text on the command line:
Unix/DOS> python plotf.py "exp(-0.2*x)*sin(2*pi*x)" 0 4*pi | |
 | Program:
from scitools.all import * formula = sys.argv[1] xmin = eval(sys.argv[2]) xmax = eval(sys.argv[3]) x = linspace(xmin, xmax, 101) y = eval(formula) plot(x, y, title=formula) |
| Thanks to eval, input (text) with correct Python syntax can be turned to running code on the fly |
