X04 - Input/Output Utilities


Chapter Introduction
X04AAF Returns or sets a unit number for error message
X04ABF Returns or sets a unit number for advisory messages
X04BCFP Reads a real general matrix from an external file (stored in its natural, non-distributed form) into an array in a cyclic 2-d block distribution on 2-d logical processor grid, used for the F07 and F08 ScaLAPACK routines
X04BDFP Outputs a real general matrix stored in a cyclic 2-d block distribution on a 2-d logical processor grid to an external file (in its natural, non-distributed form), used with the F07 and F08 ScaLAPACK routines
X04BFFP Outputs a set of real general matrices distributed on a 2-d logical processor grid, used with the F02 routines
X04BGFP Reads a general real matrix from an external file (stored in its natural, non-distributed form) into an array in a cyclic 2-d block distribution on a 2-d logical processor grid, used for the F04 (Black Box) routines
X04BHFP Outputs a general real matrix stored in a cyclic 2-d block distribution on a 2-d logical processor grid to an external file (in its natural, non-distributed form), used with the F04 (Black Box) routines
X04BRFP Reads a complex general matrix from an external file (stored in its natural, non-distributed form) into an array in a cyclic 2-d block distribution on 2-d logical processor grid, used for the F07 and F08 ScaLAPACK routines
X04BSFP Outputs a complex general matrix stored in a cyclic 2-d block distribution on a 2-d logical processor grid to an external file (in its natural, non-distributed form), used with the F07 and F08 ScaLAPACK routines
X04BUFP Outputs a set of complex general matrices distributed on a 2-d logical processor grid, used with the F02 routines
X04BVFP Reads a general complex matrix from an external file (stored in its natural, non-distributed form) into an array in a cyclic 2-d block distribution on a 2-d logical processor grid, used for the F04 (Black Box) routines
X04BWFP Outputs a general complex matrix stored in a cyclic 2-d block distribution on a 2-d logical processor grid to an external file (in its natural, non-distributed form), used with the F04 (Black Box) routines
X04YAFP Outputs a real dense vector, distributed conformally to a sparse matrix on a logical grid of processors, to an external file
