範例：2D 繪圖中的參數曲線

繪製座標為一或多個參數函數的曲線點。

一個參數

1. 使用 sin 函數，以參數 a 的形式定義函數 x 與 y：

2. 繪製 y (對照 x)。至於參數曲線，會在演算法決定的區域上繪製 500 個點。當您變更繪點數目時，區域也會隨之變更。

兩個參數

1. 設定數據點數目。

2. 定義每個數據點的角度及半徑。

3. 定義參數化座標向量。

4. 使用 augment 函數，將上述值記錄在矩陣中，以便重複使用或寫為外部檔案以供其他應用。

5. 使用 stack 函數，將標題新增至矩陣。

6. 繪製 y (對照 x)。您可修改值域變數 i 的定義，以變更繪點。
