Matrix Matrix to decompose (Am. or Eu. data†). •
tol, klass Tolerance, n. of histogram classes. •
Show values Shows the coordinates of the graph. •

Computes the Cholesky decompositions of the given symmetric positive definite matrix, A: as A = LCh LChT; and as A = L D LT. ('T' means 'transpose', but is indicated by prime in the results.) A symmetric positive definite matrix, A is such that xTAx > 0 (x ≠ 0). (It has positive diagonal elementws.)


† Am. or Eu. data: data can be given in American (Am.) or European (Eu.) style (such as in 'csv' files), i.e., with decimal mark point (e.g., 12.3, 4.7...) or comma (e.g., 12,3; 4,7...) and optional coherent separators (such as tab).
