How to use Sap2000 api Matlab ?

Hello

I work on a project, and I need programming with Matlab and Run in Sap2000. But when I use code one message happen: "Warning: ActiveX - attempt to convert unsupported SAFEARRAY type failed - substituting NAN "

how I can solve that?

my code:

clc; clear all;
x=(0.645*10^-4)+rand(10,1)*(50-0.645)*10^-4;
%% Start Sap2000
feature('COM_SafeArraySingleDim', 1); feature('COM_PassSafeArrayByRef', 1);
SapObject = actxserver('Sap2000v16.SapObject');
SapObject.ApplicationStart; ret=SapObject.SapModel.InitializeNewModel; ret=SapObject.SapModel.File.OpenFile('C:\Users\ali\Desktop\EXAM\EXAM01.sdb');
% SapObject.ApplicationStart(2, 1, 'C:\Users\ali\Desktop\EXAM\EXAM01.sdb'); SapModel= SapObject.SapModel;
%% Modify the sections area
 for k=1:1:10

     ret=SapModel.PropFrame.SetChannel( num2str(k) , 'folad' , x(k,1)^0.5 , x(k,1)^0.5 , 0.9*x(k,1)^0.5 , 0.4*x(k,1)^0.5 );

 end
%% Save new model
ret=SapModel.File.Save('C:\Users\ali\Desktop\EXAM\EXAM01.sdb');
%% Run analisis
ret=SapObject.SapModel.Analyze.RunAnalysis;
%% Get Stress from Sap2000
ret = SapObject.SapModel.Results.Setup.DeselectAllCasesAndCombosForOutput; ret = SapObject.SapModel.Results.Setup.SetCaseSelectedForOutput('DEAD');
Name = '1'; Element = 1; NumberResults = 0; Obj = cellstr(' '); ObjSta = zeros(1,1,'double'); Elm = cellstr(' '); ElmSta = zeros(1,1,'double'); LoadCase = cellstr(' '); StepType= cellstr(' '); StepNum = zeros(1,1,'double'); P = zeros(1,1,'double'); V2 = zeros(1,1,'double'); V3 = zeros(1,1,'double'); T = zeros(1,1,'double'); M2 = zeros(1,1,'double'); M3 = zeros(1,1,'double');
[ret, NumberResults, Obj, ObjSta, Elm, ElmSta, LoadCase, StepType, StepNum, P, V2, V3, T, M2, M3] = SapObject.SapModel.Results.FrameForce(Name, Element, NumberResults, Obj, ObjSta, Elm, ElmSta, LoadCase, StepType, StepNum, P, V2, V3, T, M2, M3);
disp(P);
