我正在尝试编译这种代码:

def my_func(double c, int m):
    cdef double f[m][m]

    f = [[c for x in range(m)] for y in range(m)]
    ...

提出:

Error compiling Cython file:
------------------------------------------------------------
def grow(double alpha, double beta, double gamma, int m, int s):
    cdef double f[m][m]
                     ^
------------------------------------------------------------
test.pyx:6:22: Not allowed in a constant expression

之后我假设我不能在指向的地方使用变量,我尝试使用数值:

def my_func(double c, int m):
    cdef double f[500][500]

    f = [[c for x in range(500)] for y in range(500)]
    ...

但后来我得到:

Error compiling Cython file:
------------------------------------------------------------
    f = [[beta …
