プロットの更新に問題があります。基本的に、3 つのサブプロットを持つ図を作成する関数があります。次に、図の作成関数を実行してプロットを更新する別の関数があります。3D データで読み込みに時間がかかるため、ループごとに新しいグラフを作成しないように更新することが重要です。
問題は、2 番目のサブプロットにあります。slice() を使用して 3 つの画像 (3 つのスライス) を読み込み、位置ベクトルもプロットしたいと考えています。最初に位置ベクトルを (0,0,0) に設定してから、「XData」、「YData」... をそれぞれの値に設定することでループ内で更新できると考えました。何らかの理由で機能せず、「タイプ 'double' の入力引数に対して未定義の関数 'XData'」というエラーが吐き出されています。助けてください、以下はコードです、ありがとう!!!
注 --- エラーは、"%refresh plot" の後の更新プロット関数にあります。
