文中通过把自变量的某些值重新赋值为nan,绘制出非矩形区域上函数z = f( x,y)的图形；通过把函数值中的虚数重新赋值为nan,绘制出非矩形自然定义域上函数z = f( x,y)的图形。
文中通過把自變量的某些值重新賦值為nan,繪製齣非矩形區域上函數z = f( x,y)的圖形；通過把函數值中的虛數重新賦值為nan,繪製齣非矩形自然定義域上函數z = f( x,y)的圖形。

Figures in the function of z = f( x,y) on non-rectangular domain can be drawn when nan is reassigned to some values of independent variables. At the same time, figures in the function of z = f( x,y) on non-rectangular natural domain can be drawn when nan is reassigned to some imaginary numbers of func-tion values.
