How can I input multiple test cases and extract the output of all test cases at once in Simulink?

I have created a simulink model , in which there is two variables and one output. For understanding, lets say it as , 3a+b = x, where a,b are input and x is the output.

In my case, i want to feed several test values for a,b and extract x for corresponding test cases. Like : 1. a=4,b=28 2. a=87, b=23 .........100. a=34, b=74

Now, i am doing it manually by feeding the input as constant block.

what function or option should I use to make all the test cases run at once & extract the outputs as graph or excel sheet?

You can use 'Signal Editor' block from Simulink Library.
