我如何用沙尔暗的 lo子写下以下的 lo子?
def kl(myA, myB, a, b):
lots of stuff that assumes all inputs are scalars
x, y = meshgrid(inclusive_arange(0.0, xsize, 0.10),
inclusive_arange(0.0, ysize, 0.10))
for j in range(x.shape[0]):
for i in range(x.shape[1]):
z[j, i] = kl(x[j, i], y[j, i])
我想做的是这样的事情。
z = kl(x, y)
但这提供了:
TypeError: only length-1 arrays can be converted to Python scalars
您仅询问Numpy,它称作 array Radio,而不是隐蔽的住宿。 广播一个阵列的微量操作功能被称为一种通用功能,即: 许多基本的消费功能属于这种性质。
您可使用numpy. frompyfunc ,将您的现有职能改为kl。
kl_ufunc = numpy.frompyfunc(kl, 4, 1)
...
z = kl_ufunc(x + 1.0, y + 1.0, myA, myB)
当然,如果你想要的话,你可以把“ufunc”(kl改为kl_ufunc,但随后将失去“kl的原始定义。 为您的目的,这可能会被罚款。

请注意,它是一系列研究广泛主题的一部分。
