What's the difference of double a[] and double[] a in cython?

Question

cdef public int myfun(double x, double y, double z[], double[] k):
    z[0] = 1.2
    z[1] = x + y
    k[0] = 1.2
    k[1] = x + y
    return 0

Do they belong to different types?

Answer 1

Nothing. Just different ways of declaring the same type of array. The syntax of which is inherited from C.
