Module reconstruct

Expand description

Reconstructing the original matrix from the decomposition.

Functionsยง

  • Computes the reconstructed matrix, given its QR decomposition, and stores the result in dst.
  • Computes the reconstructed matrix, given its QR decomposition, and stores the result in rhs.
  • Computes the size and alignment of required workspace for reconstructing a matrix in place, given its QR decomposition with column pivoting.
  • Computes the size and alignment of required workspace for reconstructing a matrix out of place, given its QR decomposition with column pivoting.
