how to calculate the indefinite antiderivative of a function in matlab

To calculate the indefinite antiderivative (i.e. integration) of a function in Matlab, you can use the "int" function from the Symbolic Math Toolbox. Here's an example of how to use it:

main.m
syms x % define the symbolic variable x
f = x^2 + 3*x + 2; % define the function to integrate
F = int(f); % integrate the function to get the antiderivative

The resulting antiderivative F will also be a symbolic expression, which you can evaluate at specific values of x using the "subs" function. Alternatively, you can use the "diff" function to verify that F is indeed the antiderivative of f:

main.m
diff(F) % this should output f(x)
