I am trying to create a 3d graph that compares each value in array X and Y for the minimum value: min(x,y)

This is what I have created so far:

x = [0:0.1:1]
y = x  
y = fliplr(y)

So, for example, when Y is 0.9, X is 0.1, etc.

Then I opened the plot tools, choose a 3d graph, clicked "add data" and chose 3d mesh. I added X to x, Y to y and for z: min(x,y)

I then received an error stating that axis z must be a matrix.
