Hey,
Check how you can integrate using bessel function:
% Define the lower limit of integration
k = 0; % Example value, replace 0 with your actual k value
% Define the anonymous function to be integrated
f = @(x) besselj(0, x) .* x.^2;
% Perform the numerical integration
L = integral(f, k, 1);
% Display the result
disp(L);
Thanks!

You need to provide the integrand as a function handle, see here - https://in.mathworks.com/help/matlab/ref/integral.html#btbbkta-1-fun
You can also make the integration a function of k, and obtain the integral value for different inputs -
fun = @(x) besselj(0,x).*x.^2;
L = @(k) integral(fun, k, 1)
L(0)
L(0.5)
However, if you want to get the integral as an expression, you will need to use symbolic integration for that - int (Note - requires the Symbolic Math Toolbox).
