Hi, I need some suggestions on deploying a C# program that uses Matlab functions.

I wrote a C# program using Visual Studio 2005 that incorporates Matlab functions. I started out with a basic program:

MLApp.MLAppClass matlab = new MLApp.MLAppClass(); 
matlab.Visible = 0;
string ans = matlab.Execute("3+5");
System.Console.WriteLine(ans);

It works fine on the development computer, but when I try to deploy it to another computer I get the following error:

Retrieving the COM factory for component with CLSID {07FB7FDD-3B80-4D41-A793-326AC619EA11} failed due to the following error: 80040154.

I did run the MCRInstaller.exe (found in the original computers installation folder) on the second computer, but I still have the above error. Any help or suggestions would be much appreciated. Thanks!

I figured it out. Basically you can't do it that way unless all computers have a full installation of Matlab. Instead you have to use Matlab's deploytool function to compile and make an application from Matlab. I ended up porting all my c# code to matlab .m scripts and compiling it as a .NET assembly using deploytool.

You can also use the MWArray class to pass variables between c# and Matlab functions. I found this full example very helpful in my development: http://www.mathworks.com/support/solutions/en/data/1-3NL1YX/index.html?solution=1-3NL1YX

Just do everything they do in that example and it should make sense. Good luck.
