Make a matrix with ones and if

Hi, I have a pretty simple question, but are kinda bad with ones(). I need to make a special matrix, for example, I have a 4 meter long and 2 meter width boat.

nx= 8     %Number of slices for x
hx= 4/nx  %Steplenght for x

same for y
ny=8  %Number of slices for y
hy=2/ny %steplenght for y

I want a matrix:

                     A=[0 0 0 0 0 0 0 0
                        0.5 0.5 0.5 0.5 0.5 0.5 0.5 0.5
                        1 1 1 1 1 1 1 1   osv]

so the number of rows will be nx+1 points, with x0=1, x1=xo+hx, x2=x1+hx and the number of columns will be ny+1 points, with the same value in each row.

A=[x0 x0 x0 x0(ny-times)
  x1 x1 x1 x1(ny times)
  x2 x2 x2 x2(ny-times) 
for nx+1 rows)

I'm gonna continue take values from a function and want a 100x100 matrix so I really need help with the ones() in the matrix. A=ones(x0+1, ny) didn't work.

   xx=(0:nx)*hx +x0;
   yy=(0:ny-1)*hy +y0;

   [A,B]=ndgrid(xx,yy);
