error to get the answer by Kronecker

function K = kronecker(A,B)
if ~issparse(A) && ~issparse(B)
if ~ismatrix(A) || ~ismatrix(B)
error('kronecker:TwoDInput','Inputs must be 2-D.');
end
% Both inputs are full, result is full. This is faster than
% MATLAB stock kron (indexing based)
[ma, na] = size(A);
[mb, nb] = size(B);
A = reshape(A,[1 ma 1 na]);
B = reshape(B,[mb 1 nb 1]);
K = bsxfun(@times,A,B);
K = reshape(K,[ma*mb na*nb]);
else % One of the input matrix is sparse
% Call MATLAB stock KRON
K = kron(A,B);
end
how can i solve the error ?

What input you tried? Waht error you get?
What error? You have not shown us any error message, and you have not shown us how you are calling this or what the size() or class() of the inputs are.
need more details about the error what is shown???
lamda=0.2
mu=1-lamda
A=[-(lamda1+lamda2) mu2 mu1 0;lamda2 -(mu2+lamda1) 0 mu1;lamda1 0 -(lamda2+mu1) mu2;0 lamda1 lamda2 -(mu1+mu2)];
B=[1;0;0;0];
Undefined variables lamda1, lamda2, mu1, mu2
You set variables lamda and mu but you do not use them.
You still have not indicated what error you are observing.
copy the content on the command window after getting the error and post it otherwise we can't help you
