 | Fill a NumPy array with function values:
n = 2000
a = zeros((n,n))
xcoor = arange(0,1,1/float(n))
ycoor = arange(0,1,1/float(n))
for i in range(n):
for j in range(n):
a[i,j] = f(xcoor[i], ycoor[j]) # f(x,y) = sin(x*y) + 8*x
|
| Fortran/C/C++ version: (normalized) time 1.0 |
| NumPy vectorized evaluation of f: time 3.0 |
| Python loop version (version): time 140 (math.sin) |
| Python loop version (version): time 350 (numarray.sin) |
