After reading the MATLAB Integration topic, you will able to solve problems based on integration in MATLAB, and you will also understand how to use built-in function quad to calculate the integration.
Integration is very common mathematical operation. MATLAB has a built-in function quad to calculate the integration.
quad
The quad function uses the adaptive Simpson method of integration The general form of quad function is:
General Form:
q=quad(‘function_name’,a,b)
where,
- q is the result of integration.
- function_name is the function to be integrated.
- a,b are the integration limits.
Example
Aim (1): To integrate f(x) given below using function quad, in MATLAB.
$f(x) = \int\limits_0^1 {\cos (x)dx} $
Program (1):
q=quad('cos',0,1)
Output (1):
q = 0.8415
