MATLAB 3D meshz()

meshz() is a function in MATLAB that creates a wireframe mesh plot of a surface in 3D. The mesh is plotted using x, y, and z vectors, and is visualized as a grid of rectangular faces.

Syntax
meshz(x, y, z)
meshz(z)
meshz(x, y, z, c)
meshz(ax, ...)
h = meshz(...)
Arguments
  • x: A vector containing the x coordinates of the surface to be plotted. This can also be a matrix where each row represents the x coordinates of the vertices of a z surface.
  • y: A vector containing the y coordinates of the surface to be plotted. This can also be a matrix where each column represents the y coordinates of the vertices of a z surface.
  • z: A matrix containing the z coordinates of the surface to be plotted. The matrix should have the same number of rows as x has elements and the same number of columns as y has elements.
  • c: A matrix of RGB color values or a color string that specifies the color of each face. This must be the same size as z, typically a 2D array.
Example
% create a grid of points at which to evaluate a sinc function
[x, y] = meshgrid(-5:0.5:5);

% calculate the z-values of the sinc function at each grid point
z = sinc(sqrt(x.^2 + y.^2));

% plot the surface using `meshz()`
meshz(x, y, z);

% set the view and label the axes
view([-25, 30]);
xlabel('x');
ylabel('y');
zlabel('z');

Output

Mesh plot of a sinc function in 3D created with meshz()

Conclusion

meshz() is a powerful function in MATLAB that allows programmers to easily create wireframe mesh plots of surfaces in 3D. With this function, programmers can visualize complex data in a clear and concise manner, making it an essential tool in the data visualization toolbox.
