Method: NMatrix#gesdd

Defined in:
lib/nmatrix/math.rb

#gesdd(workspace_size = nil) ⇒ Object

call-seq:

gesdd -> [u, sigma, v_transpose]
gesdd -> [u, sigma, v_conjugate_transpose] # complex

Compute the singular value decomposition of a matrix using LAPACK’s GESDD function. This uses a divide-and-conquer strategy. See also #gesvd.

Optionally accepts a workspace_size parameter, which will be honored only if it is larger than what LAPACK requires.
