MATLAB: Improper assignment with rectangular empty matrix ERROR!

findindices

I ran this small code to get the indices for the matching values of b in matrix A. The output throws an error.
a = [1 2 3 4];
b = [2 3 4 5];
 for i = 1:length(b)
   c(i) = find(a == b(i));
end
% —————- OUTPUT ————— %
Improper assignment with rectangular empty matrix.
Error in IndicesOfcomputedValues (line 5)
     c(i) = find(a == b(i));

Best Answer

[idx,values] = ismember(b,a) %returns values and logical index of b in a 
index=find(ismember(b,a)) returns linear index of b in a
