Good day everyone,
I need help with the fuction - neighbor in Simulink/MATLAB. During each time step, the choosen node changes in the model and thus the number of neighbour connection to the node; sometimes its 3 and sometimes its 2 or 1. But MATLAB shows this as an error. I am using MATLAB 2021a. I hope some expericed member in the community can help me with this.
Error:
Size mismatch for MATLAB expression '<output of neighbors>'. Expected = 3x1 Actual = 2x1

MaxNeigh = 3;
neigh = zeros(MaxNeigh,1);
coder.varsize('neigh', [MaxNeigh 1], [1 0]); %second dimension is fixed
neigh = neighbors(G);
