Solving a Riccati equation via Schur decomposition in the versions later than MATLAB 7.0

Hi, I was using ric_schr (Mu Analysis and Synthesis Toolbox) command in MATLAB 7.0 to solve riccati equation via schur decomposition. However, this command (as well as the toolbox) is missing in later versions of MATLAB such as MATLAB 7.6.0 (R2008a). Is there any other substitute for ric_schr in the subsequent versions?

I find evidence that ric_schr become part of the Robust Control Toolbox, but the function of that name does seem to have disappeared.
Possibly the current replacement function would be http://www.mathworks.com/help/toolbox/robust/ref/bstmr.html

Could you post the error message you are receiving when calling ordschur? I don't see a reason why it wouldn't work in a script.

I use it in the simulink/matlab function. schur is working well but if we type ordschur , it is not working and there is error message .
Undefined function or variable 'ordschur'.
Function 'shurrmethod ' (#44.186.213), line 13, column 1: "[U,S]=ordschur(Ud,Sd,'lhp')" Launch diagnostic report.
