Excel to Matlab to Simulink

data = xlsread('Mappe1'); breakpoints1 = data(1:end,1)'; breakpoints2 = data(1:end,2)'; Mappe1 is an excel file with 2 columns have integer values. 1st column with values 1,3,5,8 and 2nd column with values 2,2,5,7. I created 2 separate variables from this excel file. breakpoints1 = 1,3,5,8 and breakpoints2 = 2,2,5,7. Now I want to import these values from the workspace into simulink and add them and get result back in matlab workspace. That is 1 + 2, 3 +2, 5 + 5 and 8 + 7. How can I do this. Thanking You in advance.
