I get a error in a MATLAB function block
coder.extrinsic('exist');
N=1296;
if exist('w_1','var')
W1=w_1;
else
W1=zeros(N,1);
end

Because 'exist' return a double value and 'if' need to follow a logical value.
you can modify the code like this:
if isequal(exist('w_1','var'),1)
W1=w_1;
else
W1=zeros(N,1);
end
