[TRNSYS-users] Some problem about TRNSYS calling MATLAB

Hello! I am a Chinese graduate student, and our lab uses TRNSYS to do some research about microgrid. Now we have some problem about TRNSYS calling Matlab.


(1) The m-file which was called by TRNSYS contains a function from a Matlab toolbox---yalmip. The toolbox is downloaded from Internet. But there is an error "undefined function or variable 'sdpvar'" ('sdpvar' is a function from yalmip toolbox), so the TRNSYS simulation cannot run successfully.


(2) In addition, we try to use the Matlab optimization toolbox function linprog() in the m-file which was called by TRNSYS. The format is like'[x,fval]=linprog(f,[],[],Aeq,beq,lb);'. But a similar error appears again, "undefined function or variable 'fval'".


So, is it able to use Matlab toolbox function when TRNSYS calls Matlab file? Especially the toolbox installed by user. If it is, is there some extra operation?


I would be grateful i­f you can give me a r­eply at your­ earliest convenience.


Sincerely,

Qianwen Zhu
