### Test Suite

Test Status Code Input and Output
1   Fail
x = '3*x'; lower=0; upper=3; y_correct = 0; assert(isequal(myintegrate(x,lower,upper),y_correct))

Array indices must be positive integers or logical values. Error in myintegrate (line 3) y = abs(quad(f,l,u)-trapz(x,f(x))); Error in Test1 (line 4) assert(isequal(myintegrate(x,lower,upper),y_correct))

2   Fail
x = '6*x'; lower=2; upper=6; y_correct = 0; assert(isequal(myintegrate(x,lower,upper),y_correct))

Array indices must be positive integers or logical values. Error in myintegrate (line 3) y = abs(quad(f,l,u)-trapz(x,f(x))); Error in Test2 (line 4) assert(isequal(myintegrate(x,lower,upper),y_correct))

3   Fail
x = '2*x'; lower=0; upper=2; y_correct = 0; assert(isequal(myintegrate(x,lower,upper),y_correct))

Array indices must be positive integers or logical values. Error in myintegrate (line 3) y = abs(quad(f,l,u)-trapz(x,f(x))); Error in Test3 (line 4) assert(isequal(myintegrate(x,lower,upper),y_correct))
