IDENT                    (Animal Breeder's Tool Kit)               IDENT



NAME

     ident - create an identity matrix



SYNOPSIS

     ident n

     ident -m[-z](matrix file)



DESCRIPTION

     ident writes  an identity matrix  to standard output.   With

     the first form, an n  x n identity matrix will  be produced.

     n must be  a positive  integer.  With  the second form,  the

     identity matrix  produced will  have the same  dimensions as

     the  column dimension of the  specified matrix.   -z must be

     used to indicate the  input matrix file is compressed.   The

     identity matrix produced will be in DIAGONAL storage mode.



EXAMPLES

     ident 25  >I25



     will create a 25 x 25 identity matrix stored in I25.



     ident -m-zxtz >Ixz



     will  create the identity  matrix Ixz  matrix with  the same

     number  of   columns  as  the  matrix   represented  by  the

     compressed  file  xtz.Z.   If xtz.Z  contains  a 2000  x 100

     matrix, Ixz will contain a 100 x 100 identity matrix.
