I want to plot a 3D surface with the following:
y=4x-1/2
z=(14x-1)(113*x-31)/100
I know that these are each in xOy and zOy .

x=-100:0.1:100;
y=4*x-1/2;
z=(14*x-1).*(113*x-31)/100;
plot3(x,y,z)
%or
x=-100:0.1:100;
y=4*x-1/2;
[x1,y1]=meshgrid(x,y);
z1=(14*x1-1).*(113*x1-31)/100;
mesh(x1,y1,z1)

x is [0 1], y [0 1] and z>0 ...and I want to see the region were y>4*x-1/2 and z>(14*x-1)*(113*x-31)/100...
