From the range column of excel file attatched, I need to sum up each row ( columns b to h) and store the sum value in a matrix.
After I get a matrix of sum values of each row. Further the max value of that matrix is needed to be found and corresponding range to which it belongs. Could anyone help me out how I can achieve this using matlab code. The excel file is attatched.
