      Update of /cvsroot/pure-data/externals/iem/iemmatrix/abs
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv29635
Added Files:
    mtx_index2rowcol.pd mtx_rowcol2index.pd mtx_find_rowcol.pd 
    mtx_mod.pd 
Log Message:
added some useful abstractions:
...rowcol... indexing vectors/matrices can be converted to row and 
column indexing vectors/matrices.
mtx_find_rowcol ... finding nonzero row and column indices of a matrix
mtx_mod.pd ... modulo operator using division and rounding.
