Hi dear, I execute this program:
syms S;
A=1/(S+1);
B=2/(S+3);
Result=A+B
but result is:
Result =
1/(S + 1) + 2/(S + 3)
How can i change result to become format like below?
Result =
(3*S)/( S^2+4*S+3)

Hi Majid,
Please note that; with the given values, the result of adding A and B should be -
(3*S) + 5/( S^2+4*S+3)
Assuming that is the desired result, you can use the "collect" function to simplify the equation.
syms S;
A=1/(S+1);
B=2/(S+3);
Result=A+B
Result = 
Result = simplify(Result)
Result = 
Result = collect(Result, S)
Result = 
Refer to the following MathWorks documentation for more details on "collect" function:
