slmetric_pw_blks

PURPOSE

SLMETRIC_PW_BLKS Compute the pairwise metrics in a blockwise manner

SYNOPSIS

function slmetric_pw_blks(X1, X2, ps, dstpath, mtype, varargin)

DESCRIPTION

SLMETRIC_PW_BLKS Compute the pairwise metrics in a blockwise manner

 $ Syntax $
   - slmetric_pw_blks(X1, X2, ps, dstpath, mtype, ...)

 $ Arguments $
   - X1:       the first sample matrix
   - X2:       the second sample matrix
   - ps:       the partition structure of the score matrix
   - dstpath:  the destination path
   - mtype:    the metric type

 $ Description $
   - slmetric_pw_blks(X1, X2, ps, dstpath, mtype, ...) computes the 
     pairwise metric values for large dataset in blockwise manner.
     Each block of scores are computed respectively and stored in files.
     This function is an extension of slmetric_pw to support 
     blockwise score computation. 
     Please refer to slmetric_pw and slpwcomp_blks for more information
     on the usage.
