API - Load MathCAD Matrix with JScript

Does anybody know the correct code for reading out matrix content with JScript in MathCAD when loading it through the API? 

 

This is the MathCAD simplified example in MathCAD Prime 11.

This is the code in the button:

Reading a matrix value like this works excellent when loading the Matrix as a normal input variable without API.

 

Other API functions works fine, like for instance Worksheet.Output.GetValue("EampleNumber").RealResult

Hi,

Try matrixFirstValue = matrix(0, 0)

Cheers

Hi,

Thank you for your proposal. 

 

Unfortunately I get another error message: "Object doesn't support this property or method".

 

I tried both comma and dot as separator just to make sure.

I'm not sure that your variable matrix is a proper JScript array.  I think it might be a different kind of object.

 

Try result = matrix.GetMatrixElement(0, 0, mydata);  (result and mydata are arbitrary names)

(Any chance you could post the worksheet with your example, please?  I've probably made a typo as I can't get the number of rows or columns, let alone a matrix value)
