Subject: [PATCH] [Chapter 5] Update the matrix function for jagged Arrays

We may loop for the number of rows and create an array with the number of columns, not the opposite.

 for (var i=0; i < columns; i +=1) {
        jaggedarray[i]=new Array(rows);
    }

This loop will work as the columns and rows are equal, But if we want to create a jagged Array with 2 Rows and 3 Columns, this will not give us the expected result
