### Test Suite

Test Status Code Input and Output
1   Fail
x = '5/(s+2)'; y_correct = 2.5; assert(isequal(DC_gain(x),y_correct))

Error in solution: Line: 5 Column: 1 This statement is not inside any function. (It follows the END that terminates the definition of the function "DC_gain".)

2   Fail
x = '5/(s+5)'; y_correct = 1; assert(isequal(DC_gain(x),y_correct))

Error in solution: Line: 5 Column: 1 This statement is not inside any function. (It follows the END that terminates the definition of the function "DC_gain".)

3   Fail
x = '5/(2*s+5)'; y_correct = 1; assert(isequal(DC_gain(x),y_correct))

Error in solution: Line: 5 Column: 1 This statement is not inside any function. (It follows the END that terminates the definition of the function "DC_gain".)

4   Fail
x = '10/(2*s+5)'; y_correct = 2; assert(isequal(DC_gain(x),y_correct))

Error in solution: Line: 5 Column: 1 This statement is not inside any function. (It follows the END that terminates the definition of the function "DC_gain".)
