How i get the details of result from sap2000 with matlab

i wrote a Matlab code to access Sap2000 v22 trial version. this code can start the program and open a structure file and analyze it and then design the steel elements. Up to here all is good. In here start a problem for me. i try to get the detail of the result for example "ffa" values or "P" values. and i use this code for this problem;

...

NumberItems=0;

FrameName=cellstr(' ');

Value=cellstr(' ');

[~,~,~,TableS,NumberSItems,FrameNameS,ValueS] = SapModel.DesignSteel.GetDetailResultsValue( ...

"8", SAP2000v1.eItemType.Objects, 2, "DesignSect", NumberItems, FrameName(), Value());

I get this error;

" No appropriate method, property, or field 'GetDetailResultsValue' for class 'SAP2000v1.wDesignSteel'. "

and if i change the code like this;

NumberItems=0;

FrameName=cellstr(' ');

Value=cellstr(' ');

[~,~,~,TableS,NumberSItems,FrameNameS,ValueS] = DesignSteel.GetDetailResultsValue( ...

"8", SAP2000v1.eItemType.Objects, 2, "DesignSect", NumberItems, FrameName(), Value());

I get this error;

No method 'GetDetailResultsValue' with matching signature found for class 'SAP2000v1.cDesignSteel'.

What is my fault at this code? Thank You

Hello,

The errors you're encountering suggest that there is either a mistake in the method name or the way you are calling it. The error messages indicate that MATLAB cannot find a method called ‘GetDetailResultsValue’ for the ‘DesignSteel’ class in the SAP2000v1 API.

Here is a generic example of how you might correctly call a method from the SAP2000 API in MATLAB:

% Initialize the SAP2000 application 
SapObject = actxserver('SAP2000v22.SapObject'); 
SapModel = SapObject.SapModel; 

% Start SAP2000 application 
ret = SapObject.ApplicationStart(); 

% Open an existing model 
ret = SapModel.File.OpenFile('path\to\your\model.sdb'); 

% Run analysis 
ret = SapModel.Analyze.RunAnalysis(); 

% Obtain results - this is where you need to adapt based on correct API usage 
% For example, if GetDetailResultsValue is a correct method, ensure you have the right instance: 
DesignSteelInstance = SapModel.DesignSteel; % Get the DesignSteel instance 

% Now call the method on the instance with the correct parameters 
[ret, TableS, NumberSItems, FrameNameS, ValueS] = DesignSteelInstance.GetDetailResultsValue(...); 

Additionally, ensure that the COM object SAP2000v22.SapObject matches the version of SAP2000 you are using. If you're using a different version, you'll need to adjust the object name accordingly.
