MATLAB: Simulink : Get handle of a Matlab-Function block, inside Matlab-Function itself

block handlefrominsideitselfmatlab functionsimulink

Hello,

Is there a way to get handle of a Matlab-Function Simulink block inside of the Matlab-Function itself?

Thanks!

I would think so, just try handle=get_param(Block,'handle') where "Block" is the full path of the MATLAB function block in your Simulink model.

This is not really an error. It just tells that you need to change the sampling rate of this block from continuous to discrete. Just click the "Fix" button on the first box under "Suggested actions" and the error will be fixed.

You need the symbolic toolbox in order to do this, and you need to declare your free variable with either a sym() or syms() call.

Please also note that you cannot take the derivative of a mathematical function over a range.

If you are trying to do numeric derivatives then you should recode as something like:

function df = derivate(f)
  x = -20:20;
  df = diff(f(x));
end

and you would then call it with a function handle, such as calling

derivate(@(x) 3*x+5)
