[TRNSYS-users] Error in calling Matlab

[mahdi shahrestani]

Hello every body 
 
I have a problem in calling Matlab .
When I want to run the “calling matlab” which is a predefined example of Trnsys, this error comes up. 
 
Message  : Your input file uses Type 155 (Calling Matlab). "Type155.dll" was found but could not be loaded. Please make sure that a supported version of Matlab is installed and that Matlab's "bin\win32" folder is on Windows' search path
 
Matlab 2009a is instulled on my machine.
Could any body have a suggestion to solve it?
 
Many thanks for your time
Mehdi
