How to select value

clear Z=[-4:1:2];H=[0:1:4]; [xx,yy]=meshgrid(Z,H); zz=0.4166+0.0456.*yy-0.2343.*xx; if zz>=1 then zz=1 end if zz<=0 then zz=0 figure surf(xx,yy,zz) I want the value staying at (0,1), how to make this happen? and why this program doesn't work

clear
Z=[-4:1:2];
H=[0:1:4];
[xx,yy]=meshgrid(Z,H);
zz=0.4166+0.0456.*yy-0.2343.*xx;
zz(zz>1)=1
zz(zz<0)=0
figure
surf(xx,yy,zz)

thanks you! and how to make 'if' sentence work in this context?

[Azzi Abdelmalek]

clear
Z=[-4:1:2];
H=[0:1:4];
[xx,yy]=meshgrid(Z,H);
zz=0.4166+0.0456.*yy-0.2343.*xx;
for k=1:numel(zz)
  if zz(k)>1
      zz(k)=1
  elseif zz(k)<0
      zz(k)=0
  end
end
figure
surf(xx,yy,zz)

Answer 2

[TAMILAN]

clear

Z=[-4:1:2];

H=[0:1:4];

[xx,yy]=meshgrid(Z,H);

zz=0.4166+0.0456.*yy-0.2343.*xx;

for k=1:numel(zz)

if zz(k)>1

zz(k)=1

elseif zz(k)<0

zz(k)=0

end

end

figure

surf(xx,yy,zz)
