i want fsolve to calculate the output for different uc each time (increasing uc by 0.001 each time). each output from fsolve should be sent to a simulink model seperatly. so i set a loop to do so, but i believe that at the currenty constellation (if it will work)will just calculate 1000 different values? is there a way to send out the values seperately?
if not, how can i create a parameter uc. that goes from 0 to say 1000? i tried uc=0:0.1:1000, but again, the demension doen't seem to fit.
how do i create a function that takes the next element of a vector/matrix each time the function is called?
best regards

function Result = f(YourArray)
persistent iteration_number
if isempty(iteration_number); iteration_number = 0; end
iteration_number = iteration_number + 1;
if iteration_number > numel(YourArray);
Result = [];
iteration_number = []; %reset for next cycle
return;
end
Result = some expression in YourArray(iteration_number)
end
Please also read the documentation for fsolve() as you cannot pass in parameters the way you do. Please see the section about parameterizing the function.

Write a Level 2 S function if necessary.
There is a lot about Simulink that I have not put together mentally yet, as I do not have access to it myself.
