Mesh Plotting in Matlab

Hello, I am trying to perform a simple finite element analysis. To create a mesh, I am using

xArray = 0 : 0.1 : 1;
yArray = 1 : 0.2 : 2;
[X, Y] = meshgrid(x, y)

Now, I want to plot it like

What command is use for this purpose?

Answer 1

[Precise Simulation]

The following will plot quadrilaterals from your grid (if you prefer triangles you can use the patch command)

    x = 0 : 0.1 : 1;
    y = 1 : 0.2 : 2;
    [X, Y] = meshgrid(x, y)
    h = mesh(X,Y,ones(size(X)));
    set(h,'marker','o','markeredgecolor','k','markerfacecolor','r', ...
        'facecolor',[.9 .9 .9])
    grid off
    view(0,90)
    axis equal
