非矩形区域上图形绘制的MATLAB实现

Applying MATLAB to Draw Figures on Non-rectangular Domain

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.

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 ofz = f（x,y） on non - rectangular natural domain can be drawn when nan is reassigned to some imaginary numbers of function values.
