Evaluating an Integral
To evaluate an integral you must first define the function y = f(x). Follow the simple steps below.
Example
>function y= f(x)
y= sin(x);
endfunction
># We are trying to integrate x from 0,2.
>area=quad("f",0,2)
area =1.4161
This example shows where the correct answer is 1.4161.
