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