cratepy.tensor.matrixoperations.get_condensed_matrix

get_condensed_matrix(matrix, rows, cols, is_check_indexes=False)[source]

Perform condensation of matrix given a set of rows and columns.

Parameters:

  • matrix (numpy.ndarray (2d)) – Matrix to be condensed.

  • rows (numpy.ndarray (1d)) – Indexes of rows to keep in condensed matrix.

  • cols (numpy.ndarray (1d)) – Indexes of columns to keep in condensed matrix.

  • is_check_indexes (bool, default=False) – If True, then check validity of condensed rows and columns indexes before performing matrix condensation. May yield non-negligible overhead cost when condensing large matrix.

Returns:

matrix_condensed – Condensed matrix.

Return type:

numpy.ndarray (2d)
