110471 Matrix Subroutines Version: January 1981 Submitted by: H. W. Holdaway, C.S.I.R.O. Division of Textile Physics, Australia Operating System: RT-11 V2 or later Source Language: FORTRAN IV Memory Required: 12392 bytes Keywords: Mathematical Abstract: Seventeen FORTRAN subroutines have been prepared for the more common matrix operations. Matrix multiplication is available for the products A.B, A .B, A.B . Singular value decomposition and generalized inversion are provided. A subroutine MXTRAP transposes the elements of A(M,N) within the same storage space. Notes: To avoid problems compile in threaded code. Restrictions: Only two matrices at a time may be multiplied. Intermediate products must be stored. Media (Service Charge Code): Write-Up (AA), Source Listing (BA), Two RX01 Diskettes (KB) Format: RT-11, 600' Magnetic Tape (MA) Format: RT-11
