assume a is a ndarray object:

a = np.array([1.0, 2.0, 3.0])

  1. mxGetNumberOfDimensions: a.ndim

  2. mxIsDouble: a.dtype == float

  3. mxGetM: a.shape[0]

  4. mxCreateDoubleMatrix: np.zeros(...)

  5. mxGetPr: a.data or a.ctypes.data

  6. lookupspline: sorry, I don't know what is this, there are some spline relate functions in scipy.interpolate.
