如何实现两个变量区间的分段函数呢。
显示 更早的评论
x=-2:0.01:2;
x=x+(x==0)*eps;
y=-2:0.01:2;
%y=y+(y==0)*eps;
[X,Y]=meshgrid(x,y);
m=1;
for xx=x，yy=Y
if(xx<=2&xx>0&&yy<=2&yy>0)
B=Y./X;
elseif(xx>=-2&xx<0&&yy<=2&yy>0)
B=Y./X+pi/2;
elseif(xx>=-2&xx<0&&yy>=-2&yy<0)
B=Y./X+pi;
else
B=Y./X+3*pi/2;
end
Z=m.*atan(B);
figure(1);
meshc(x,y,Z);
比如上边程序，红色字应该怎么改呢，如果没法改应该怎么正确写呢，求大佬解答

参考代码：
clear;clc
dt = 0.01;
m = 1;
for a = 1:4
if a == 1
x = 0:dt:2; y = 0:dt:2;
elseif a == 2
x = -2:dt:0; y = 0:dt:2;
elseif a == 3
x = -2:dt:0; y = -2:dt:0;
elseif a == 4
x = 0:dt:2; y = -2:dt:0;
end
[X,Y] = meshgrid(x,y);
if a == 1
B = Y./X;
elseif a == 2
B=Y./X+pi/2;
elseif a == 3
B=Y./X+pi;
elseif a == 4
B=Y./X+3*pi/2;
end
Z = m.*atan(B);
meshc(X,Y,Z)
hold on
end
