Hi, I need to call Matlab from GenXPro software (in which we code with Java) to calculate something and return it to the original software. To do this the first condition is that the programming language (e.g. Matlab) support the creation of COM components which is the feature of many of scripting languages. So, I would be thankful to answer my questions in the subject; I search for that, but the answers are not consistent.

Many Thanks, Jamal

Matlab implements a COM server, so you can indeed control matlab from any software that supports instantiating COM components. it's actually well documented in the help.

However, as far as I know, Java does not natively allow you to interface with COM.

在 MATLAB Online 中打开

It would have been useful if you'd linked the correct page. Anyway, this may work:

var matlab = new ActiveXObject("Matlab.Application");
matlab.PutWorkspaceData("gxptTarget", "base", gxptTarget);
matlab.PutWorkspaceData("gxptOutput", "base", gxptOutput);
matlab.PutWorkspaceData("gxptParams", "base", gxptParams);
matlab.PutWorkspaceData("gxptModelInfo", "base", gxptModelInfo);
matlab.Execute("result = somefunc(gxptTarget, gxptOutput, gxptParams, gxptModelInfo);")
return matlab.GetWorkspaceData("result", "base");
