how touse sap2000 API getnamelist

Hello

I'm working on a project and I need to get all the point names (because SAP doesen't name points in an order) from the SAP model in matlab so i can use them after that.

My code so far in this section is:

feature('COM_SafeArraySingleDim', 1);

feature('COM_PassSafeArrayByRef', 1);

SapObject = actxserver('Sap2000v15.SapObject');

SapObject.ApplicationStart;

Sap = SapObject.SapModel; 

% open and run file
ret = Sap.File.OpenFile('F:\Faculta\_Dizertatie\matlab\DDBD\SAP\exemplu cadru.sdb');

ret = Sap.Analyze.RunAnalysis();

countP= Sap.PointElm.Count;

PCTs= zeros(1,1); (I tried alot here, but haven't found the right one)

[ret,PCTs] = Sap.FrameObj.GetNameList(countP,PCTs);

The count is getting the corect number of points but I don't get the list of point names

And i also have a question, what is the diference between element and object (point, frame...)

I keep getting as a result => rect = 0 ; PCTs = 104

If someone can tell me what am i doing wrong I will be verfy gratefull.

You may try this:

PCTs = cellstr(' ');
[ret,PCTs] = Sap.FrameObj.GetNameList(countP,PCTs);

I guess that the point ID is string and you should store it in cell in case if they do not have the same length.
