Cholesky Decomposition. More...

Device pointer interface: Cholesky decomposition
Parameters: [out] d_R Matrix of Size: (n, n). [in] n Width of the input matrix d_A. [in] d_A Input square matrix of width n. [in] is_upper Flag to specify the format out the required output. d_R is upper triangular if is_upper is true. d_R is lower triangular if is_upper is false. [in] batch Number of tiles of input being handled.
