Which block should be used for numel function in simulink?

I want to express code accuracy = sum(predicted_labels == actual_labels)/numel(actual_labels) in simulink.

I choose "sum of Elements" for the function "sum(predicted_labels == actual_labels)".(I'm not sure. Is it correct?)

Which block should be used for numel function(numel(actual_labels) ) in simulink?

Answer 1

[Sulaymon Eshkabilov]

I don't know if there is any Simulink block for numel() or size(), which are handled in Simulink automatically. In your execise you shall try to use [MATLAB function] and through which you can determine the accuracy of your classification model (one output with two inputs) as you defined: accuracy = sum(predicted_labels == actual_labels)/numel(actual_labels).
