Hi Robin,

To calculate a definite double integral in MATLAB, you can use the function "integral2", which is described on the following documentation page: https://www.mathworks.com/help/matlab/ref/integral2.html

If you are looking to plot the results of a definite double integral, you can plot the results of "integral2" with various bounds, depending on your specific problem.

Alternatively, depending on what you are looking for, you could use the function "int" from the symbolic math toolbox to calculate an indefinite integral, and then plot that function.

See the documentation for the "int" function for more information: https://www.mathworks.com/help/symbolic/int.html

For general information regarding double integration in MATLAB, see the following blog post: https://blogs.mathworks.com/loren/2014/02/12/double-integration-in-matlab-methods-and-handling-discontinuities-singularities-and-more/
