Thank you very much for reading.Order status, license renewals, passcodes Hope you got some basic idea about it from this article. You can use MATLAB documentation to obtain clear idea how does it work.Īt this point I conclude my short article on ‘Symbolic Integration and Differentiation using MATLAB’. And it has two variations named ‘ integral2’ and ‘integral3’ for 2D and 3D integration as well. There is another function named ‘integral’ to perform the numerical integration using MATLAB. G(x) = int(f(x),integrate on, from, to) % gives you the integral G(x) = int(f(x),integrate on) %gives you symbolic result Now say you need to evaluate first derivative of f(x) at x = 5 then It can be calculated as follows.Ĭommand format we use is ‘int’ and the format is as follows. G(x) = diff(f(x),variable in interest, order of derivative) The MATLAB function ‘diff’is used for performing symbolic differentiation and the function format is as follows. Now let’s have a look how the symbolic differentiation is performed.

Therefore by using the command ‘pretty’we can display this in more readable format in MATLAB command line. However this equation and answer representation is bit annoying. Say If you need to evaluate f(x) at x = 10 that is f(10) then it’s simply You can clearly see that ‘x’ is a symbolic object and f(x) is a symbolic function. We can input our function to MATLAB as follows. Representing a function as reader friendly format In this small article I am going to share my experience on symbolic integration and differentiation using MATLAB. And also the proper way to display a function in MATLAB command line. While messing with MATLAB during free time I have found the method (thanks to MATLAB documentation) of performing symbolic integration and differentiation using MATLAB.
