Hi, I have to implement the following Matlab code in Simulink. To implement if-else conditions, I have used switch block. I am facing the problem in setting flags.

flag = 0; if a > 0 { c = a + b; flag = 1; } else { c = a - b; if flag == 1; { c = 0; } flag = 0; } end

Thanks

Is the problem correct? How can flag be 1 in the else condition? Can you provide the matlab code with proper indentations. Try and use the Matlab function block if the idea is to do something quick.
