msvd(1)                      Khoros                       msvd(1)

PROGRAM
     msvd - compute the Singular Value Decomposition of a matrix

SYNTAX
     msvd

     -i             input image (image)

     [-o1]          resulting U output image (image)

     [-o2]          resulting S output image (image)

     [-o3]          resulting V output image (image)

     [-V]           Gives the version for msvd

     [-U]           Gives the usage for msvd

     [-P]           Prompts for command line options

     [-A [file1]]   Creates the answer file called msvd.ans or
                    file1

     [-a [file1]]   Uses msvd.ans or file1 as the answer file

DESCRIPTION
     computes the singular value decomposition of a matrix.  If A
     is the input matrix, this program will solve the system A =
     U*S*V' for the U and V unitary matrices and S, a non-
     negative diagonal matrix, with values in descending order.

     This decomposition method is particularly useful for linear
     least squares problems and for decomposition of singular or
     ill-conditioned matrices.

REQUIRED ARGUMENTS
     -i     type: infile
            desc: input image (image)

OPTIONAL ARGUMENTS
     -o1    type: outfile
            desc: resulting U output image (image)

     -o2    type: outfile
            desc: resulting S output image (image)

     -o3    type: outfile
            desc: resulting V output image (image)
