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 elimi-
     nation.  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)
