I have a 129202×2 double and this represents different people's associations with certain "groups". On a row we have a group number (column1) och a person id (column2). I wish to create a sparse matrix when G(i,j)=1 means that person j is connected to group i. I would prefer the matrix to be symmetric. Don't send me the link to matlab sparse page, please. I don't get it.
