For a MATLAb function
function sum2 = addtwo(x,y)
sum2=x+y
end

This ought to work (I havent tested it)

%x and y are numerical objects
myMATLAB.PutWorkspaceData("transIn","base", x);
myMATLAB.PutWorkspaceData("transIn","base", y);
myMATLAB.Execute("addtwo(x,y)");
myMATLAB.GetWorkspaceData("transOut", "base", out sum2);

Thanks Ashish. That helps, where on my server should the *.m file reside?

Josh,

Anywhere, provided you 'addpath' to the directory.:

Add this line in the constructor:
myMATLAB.Execute("addpath <path to dir>");

Could you post your code?
I am not too familiar with IIS/Web services, but someone else here might
be able to help better.


Also, maybe these examples would give you some more ideas:

Or please paste this in the MATLAB command window:
web([docroot,'/techdoc/matlab_external/f135590.html'])
