Problem about code generation with Matlab function

In a matlab function,I tried to convert a continuous state space model to a discrete one:

Ts=0.005;
Ad=(eye(22)+Ap*Ts/2.0)*inv(eye(22)-Ap*Ts/2.0);
Bd=inv(eye(22)-Ap*Ts/2.0)*Bp*sqrt(Ts);
Cd=sqrt(Ts)*Cp*inv(eye(22)-Ap*Ts/2.0);
Dd=Dp+Cp*inv(eye(22)-Ap*Ts/2.0)*Bp*Ts/2.0;

but when code generation with grt.tlc, the problem report as following:

CGIR assertion 'StaticMatrixType::isa(aExpr->type()) == StaticMatrixType::isa(aExpr->rhs()->type())
log: ./cg_insanity_23.html' failed in '.\dom_core\utility\cg_sanity_checker.cpp:1317'

### Build procedure for model: 'SIMO_AdaptiveCtrl' aborted due to an error.

I wonder... if you were to comment out statements starting from the end, can you pin this down to one statement?
