chol,ANY-method

chol,gmatrix-method


Takes a square symmetric posative definite <code>gmatrix</code> object. Note that no checking for symmetry is done. An error will be thrown if the the matrix is not posative definite. Returns a <code>gmatrix</code> object that is upper triangular.

chol

A general framework for utilizing R to harness the power of NVIDIA GPU's. The "gmatrix" and "gvector" classes allow for easy management of the separate device and host memory spaces. Numerous numerical operations are implemented for these objects on the GPU. These operations include matrix multiplication, addition, subtraction, the kronecker product, the outer product, comparison operators, logical operators, trigonometric functions, indexing, sorting, random number generation and many more.
