Using kron() function within LMI toolbox environment

Hi there, How do we implement a Kronecker product kron() within the LMI toolbox environment ? I have searched the syntax of LMI toolbox and did not find anything concerning the implementation of Kronecker products.

If I implement the following code

PN=lmivar(1,[4 1]) ; P = kron((4/5)*eye(1), PN);

then it seems that the variable P cannot be recognized by the LMI program.

Thanks a lot !

Please explain your claim: "it seems that the variable P cannot be recognized" with any details.

I have contacted the author of LMItoolbox and it seems that the function kron() in Matlab cannot be applied in the LMItoolbox directly.
