mlud(1)

PROGRAM
mlud - compute the LU decomposition of a matrix

SYNTAX

mlud

-i  input image (matrix)

[-o1]
    resulting lower diagonal output matrix (image)

[-o2]
    resulting upper diagonal output matrix (image)

[-V]
    Gives the version for mlud

[-U]
    Gives the usage for mlud

[-P]
    Prompts for command line options

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

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

DESCRIPTION
computes the LU decomposition of a matrix by gaussian elimination. If A is the input matrix, this program will solve the system L*U = A for the L and U matrices. U is an upper triangular matrix, and L "nearly" lower diagonal.

REQUIRED ARGUMENTS

-i  type: infile
    desc: input image (matrix)

OPTIONAL ARGUMENTS

-o1 type: outfile
    desc: resulting lower diagonal output matrix (image)

-o2 type: outfile
    desc: resulting upper diagonal output matrix (image)
