derivatize
(num, denom)[source]¶ Method for derivatizing numerator, num, with respect to denominator, denom.
Parameters: - num (int or array-like) – The numerator of the numerical derivative function.
- denom (array-like) – The denominator of the numerical derivative function. Length n.
Returns: derivative – An
np.ndarray
instance of the derivative. Length n.Return type: rparray
Raises: ArrayError
– If denom is not array-like.See also
numpy.gradient()
- The method used to calculate derivatives
Notes
This method uses the
np.gradient
method to calculate derivatives. If denom is a scalar, resulting array will be allnp.inf
. If both num and denom are scalars, resulting array will be allnp.nan
. If either num or denom are 1d and the other is 2d, derivative will be calculated column-wise. If both are 2d, each column will be derivatized separately.
