corr2 on simulink don't code genaration

The function 'corr2' is not supported for standalone code generation. See the documentation for coder.extrinsic to learn how you can use this function in simulation.

what function can replace this function on the simulink simulation?

[Birdman]

There is the necessary function and its embedded model in a MATLAB Function in Simulink. Hope this helps. You need to have the m file and the model at the same directory.

thanks your help

sorry i use this function run on the matlab show the error message: Error using * Inner matrix dimensions must agree.

Error in Corr3 (line 5) rNum(i)=((A(i)-A_0)*(B(i)-B_0));

Error in OCR (line 55) sem=Corr3(templates(1:42,n:n+23),img_r);

[Birdman]

It should work just fine. Make sure that arrays are the same length

[Walter Roberson]

It looks to me like the inputs must be vectors?

[Birdman]

The inputs are vectors.

[tsai kai shung]

my input is array!so how to change this function

[Birdman]

Define nx1 array, which means vector.

[tsai kai shung]

how to define

[tsai kai shung]

function r = Corr2(A,B)
A = A - mean2(A);
B = B - mean2(B);
r = sum(sum(A.*B))/sqrt(sum(sum(A.*A))*sum(sum(B.*B)));
end

i use this can normal run

[Birdman]

A=[1 2 3 4] and B=[3 4 5 6]. In constant block in simulink, just type the array, don't write A=[1 2 3 4]. Write [1 2 3 4] only.

i use the BWimage input
