Hello Group,

Someone could help me with this function?

fConver[cmatrix], this function will find all subsets of rows of the rectangular matrix which have exactly one nonzero element in each column.

For example:

cmatrix=({{0,0,1,0,1,1,0},{1,0,0,1,0,0,1},{0,1,1,0,0,1,0},
          {1,0,0,1,0,0,0},{0,1,0,0,0,0,1},{0,0,0,1,1,0,1}});


fConvert[cmatrix]

the out put will be
{{{1,4},{3,5,6},{2,7}}}

Thank you All,

Johum,
