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
