Set a linear link in SAP2000 using API and Matlab

[GradUNH]

Hello!

I've been trying to change the properties of an existing linear link in SAP2000 using the API and MATLAB

I'm trying this in MATLAB:

DOF=logical(zeros(6,1));
Fixed=logical(zeros(6,1));
Ke=[1e8; 1e8; 1e8; 1e8; 1e8; 1e8];
Ce=(zeros(6,1));

ret = SapModel.PropLink.SetLinear('BaPartialAction', DOF, Fixed, Ke, Ce,0,0)

But it doesn't work! I get ret =1, meaning that there is something wrong with the input arguments in SapModel.PropLink.SetLinear.

Does anyone have a suggestion?

Thanks very much.
