Calculate the right Riemann sum of f(x)=x^2+2x-1 on the interval I=[0,2] with 4 regular portions.

I am getting this error " Execution of script riemansum as a function is not supported".Can someone help?

[Yusuf Suer Erdem]

I used it with this way. It was working properly but I was not able to select 4 regular points.

syms x
rsums(x^2+2*x-1,0,2)

The first executable word of file riemansum.m is not "function", so MATLAB considers the file to be a script that can be executed but not called.

What is the first non-comment non-blank line of riemansum.m ?
