    A mesh plot is a three-dimensional surface that has solid edge colors and no face colors. The function plots the values in matrix Z as heights above a grid in the x - y plane defined by X and Y .

  • That's because when the Y-axis is set back to normal, it affects how MATLAB displays the figure. Y is small at the bottom and large at the top, so MATLAB will show the image upside down. It turns out the Y-axis direction specifies how MATLAB displays the image; the image raster row axes is always displayed in the same direction as the Y-axis. ----- = Iso2Mesh: An Image-based 3D Surface and Volumetric Mesh Generator = ----- *Author: Qianqian Fang <q.fang at neu.edu> Department of Bioengineering Northeastern University 360 Huntington Ave, Boston, MA 02115 *Version: 1.9.0 (Century Egg) *License: GPL v2 or later (see COPYING) (this license does not cover the binaries under the bin/ directory, see Section III for more details) *URL ...
