I have a specific data and now I need to know how I can produce a matrix with the following formula: 1/2+sum of multiplications of row(i)-row(n). That is to say, I have a matrix with let say 2 columns and 3 rows and I need to produce a new matrix by calculating a value for each element (value in the cell=v(row,column). In the real matrix the number of rows and columns are 106 and 133... First the original matrix column1 column2 row1 v(1,1) v(1,2) row2 v(2,1) v(2,2) row3 v(3,1) v(3,2) And then the desired one. Read carefully, v(row, column)'s come from the upper matrix : column1 column2 row1 1/2+v(1,1)+v(1,1)*v(2,1)+v(1,1)*v(2,1)*v(3,1) 1/2+v(1,2)+v(1,2)*v(2,2)+v(1,2)*v(2,2)*v(3,2) row2 1/2+v(2,1)+v(2,1)*v(3,1) 1/2+v(2,2)+v(2,2)*v(3,2) row3 1/2+v(3,1) 1/2+v(3,2)
