symbolic variable of an integration in matlab

To create a symbolic variable for an integration in MATLAB, you can use the syms function. Here's an example:

main.m
syms x;
f = sin(x);
integrated = int(f, x);

In this example, we first declare x as a symbolic variable using the syms function. Then, we define the function f as sin(x). Finally, we use the int function to compute the integration of f with respect to x.

The variable integrated will contain the symbolic representation of the integral. You can also evaluate the result by using the eval function, or manipulate it further using other symbolic computation functions in MATLAB.
