FullyParameterizedSPAMVec.deriv_wrt_params()

Construct a matrix whose columns are the derivatives of the SPAM vector with respect to a single param. Thus, each column is of length get_dimension and there is one column per SPAM vector parameter.

Returns:Array of derivatives, shape == (dimension, num_params)
Return type:numpy array
