[SciPy-User] array creation

[elmar werling]

I need a generalized function foo(ncols, min, max, delta) for

# two component mixing ratios (ncols=2, min=0, max=1, delta=0.1)
for x1 in np.arange(0.0, 1.05, 0.1):
     x2 = 1.0 - x1
     print (x1, x2, ' = ', x1+x2)

# three component mixing ratios (ncols=3, min=0, max=1, delta=0.1)
for x1 in np.arange(0.0, 1.05, 0.1):
     for x2 in np.arange(1.0 - x1, -0.01, -0.1):
         x3 = 1.0 - x1 - x2
         print(x1, x2, x3, ' = ', x1+x2+x3)

# four component mixing ratios (ncols=3, min=0, max=1, delta=0.1)
for x1 in np.arange(0.0, 1.05, 0.1):
     for x2 in np.arange(1.0 - x1, -0.01, -0.1):
         for x3 in np.arange(1.0 - x1 - x2, -0.01, -0.1):
             x4 = 1.0 - x1 - x2 - x3
             print(x1, x2, x3, x4, ' = ', x1+x2+x3+x4)
