Expand description

Computes the reconstructed matrix, given its partial pivoting LU decomposition, and stores the result in dst.

§Panics

  • Panics if the row permutation doesn’t have the same dimension as the number of rows of the matrix.
  • Panics if the destination shape doesn’t match the shape of the matrix.
  • Panics if the provided memory in stack is insufficient (see reconstruct_req).
