Test Status Code Input and Output
1   Fail
fun = @(x) x^2; assert(abs((dquad(1,fun) - 1/3)*3)<0.01)

Error in solution Line: 6 Column: 1 This statement is not inside any function. (It follows the END that terminates the definition of the function "dquad".)

2   Fail
fun = @(x) x(1)*x(2); assert(abs((dquad(2,fun) - 0.25)*4)<0.01)

Error in solution Line: 6 Column: 1 This statement is not inside any function. (It follows the END that terminates the definition of the function "dquad".)

3   Fail
fun = @(x) 1+sin(x(1)); assert(abs((dquad(50,fun) - 1.45969769)/1.45969769)<0.01)

Error in solution Line: 6 Column: 1 This statement is not inside any function. (It follows the END that terminates the definition of the function "dquad".)

4   Fail
