Loop for contour a 3 inputs function

Hello ,

Suppose i have

function(s)=abc(x,y,z)

e.g. s= x.^2+2x.*y.*z+y^3+y.^2+5*z.^3+5*z

x1=rand(1000);

y1=rand(1000);

z1=rand(1000)

n=length(z1);

And i want for every z1=(1:n)

z1(n)=z

e.g. if the first z (z=1) I would like a contour of the function

s1= x.^2+2x.*y.*z+y^3+y.^2+5z.^3+5*1+5

contourf(x1,y1,s1). I want to do this for all z1 and i dont care defining the2 inputs functionsi care only for the contours

[KSSV]

x = linspace(-1,1) ; 
y = linspace(-1,1) ;
z = linspace(-1,1) ;
[x,y,z] = meshgrid(x,y,z) ; 

s = x.^2+2*x.*y.*z+y.^3+y.^2+5*z.^3+5*z ; 

% Use slice

xslice = [-1 0 +1];   
yslice = 0.;
zslice = 0;
slice(x,y,z,s,xslice,yslice,zslice)

perfect man it works but i also need to store each one of those contours or just to pop up after the script. Now the 3d version appears. I want each one 2 d contour
