AppDesignerにおいて、fimplicitでグラフを作成した時、その(x,y)の値をCSVファイルで取り込みたいのですが、うまく行きません。
ImplicitFunctionLineプロパティには、XDataやYDataがあるようですが、次のように記載しても、データがとれません。
また、エラーも発生しません。どこが間違っているのかご教示いただければ幸いです。
　　fimplicit(app.UIAxes,@(x,y) x.^2 + y.^2 -3, 'MeshDensity', 151, 'XData',app.XX, 'YData', app.YY);

But fimplicit does not require any data to plot.
And the XData and YData properties are Read-only. They can't be modified.
What is it that you want to plot? What is the idea/objective here?

Thank you for your quick response to my question.
I would like to get the coordinates of (x,y) on the fimplicit,
and use (x,y) for numerical analysis.

Ran in:
ImplicitFunctionLine の XData, YData プロパティは陰関数を描画した際に生成されます。
以下のようにすると、生成後の XData, YData を取得することができます。
% 陰関数を描画
figure
h = fimplicit(@(x,y) x.^2 + y.^2 -3);
% XData, YDataプロパティを取得
x = h.XData;
y = h.YData;
% 表示
disp([x', y'])
