Source function f in pde toobox

It appears that a function to represent a source f = fcoefficient(location,state) does not allow for complex inputs. I want to couple equations where the source for one of the components is a complex quantity; e.g., f(4,:) is a function of solutions of the other components. These solutions are complex.

Hello Lewis

In MATLAB, you can work with complex numbers and perform operations on them. If you want to represent a complex source function, you can define it as a function handle that takes complex inputs.

Adding a sample code for your reference

% Define the source function
f = @(location, state) complexFunction(location, state);

% Define the complex function
function result = complexFunction(location, state)
    % Perform operations on complex inputs
    result = state(1,:) + 1i*state(2,:);
end

In the code above, the "complexFunction" takes two inputs "location" and "state", where "state" is a matrix of complex solutions for other components. The function performs operations on the complex inputs and returns a complex result.
