Input

• a - Parallel array of rank greater than or equal to 2. This array contains one or more instances of a coefficient matrix A to be factored. Each A is assumed to be dense with dimensions M x N with rows counted by axis row_axis and columns counted by axis col_axis.

• row_axis - Scalar integer variable. Identifies the axis of a that counts the rows of each matrix A. For C program calls, row_axis must be >= 0 and less than the rank of a; for Fortran program calls, it must be >= 1 and not exceed the rank of a. In addition, row_axis and col_axis must not be equal.

• col_axis - Scalar integer variable. Identifies the axis of a that counts the columns of each matrix A. For C program calls, col_axis must be >= 0 and less than the rank of a; for Fortran program calls, it must be >= 1 and not exceed the rank of a. In addition, row_axis and col_axis must not be equal.
