invoke(target_sheet, 'Activate');
Activesheet = myApp.Activesheet;
cellname = 'B2';
Range = Activesheet.cells.Range(cellname,cellname);
the term Range is both a function on the MATLAB path and a constructor of the class
Range. MATLAB tries to execute the function range, which generates the error:
??? Error using ==> range
Too many input arguments.
Error in ==> MyScript at 8
Range = Activesheet.cells.Range(cellname,cellname);
To get the property value, use the get function.
For example:
Range = get(Activesheet.cells, 'Range', cellname, cellname);
