WebSep 16, 2016 · One way to do this is by using a sparse matrix. The following example creates a 10x10 zero-matrix with ones at [5,2] (row 5, col 2) and [7 5] full (sparse ( [5 7], [2 5],1,10,10)) Use full to convert it from a sparse matrix to a "full" one. Another (faster but maybe not as intuitive) alternative is to use accumarray. WebA zero matrix is a type of matrix in which all of the elements are equal to zero.
