Axis function matlab

A pseudocolor plot displays matrix data as an array of colored cells (known as faces ). MATLAB ® creates this plot as a flat surface in the x - y plane. The surface is defined by a grid of x - and y -coordinates that correspond to the corners (or vertices) of the faces. The grid covers the region X=1:n and Y=1:m, where [m,n] = size (C).

mesh (X,Y,Z) creates a mesh plot, which 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. The edge colors vary according to the heights specified by Z. mesh (Z) creates a mesh plot and uses the column and row ...This property determines how high-level plotting functions draw into an existing axes. add-- use the existing axes to draw graphics objects. replace-- reset all axes properties, except Position, ...

Axes objects are children of figure objects and parents of image, line, patch, surface, and text objects. Axes objects define a frame of reference that orients their children objects within the figure. h = axes creates the default full-window axes and returns its handle. I would rather pass a generic array ala the snip below, where parameter/value pairs are simply relayed directly to the plot function: Theme. Copy. PlotOpts.LineStyle = '-.'; PlotOpts.Color = [0 1 0]; plot (rand (10,1),PlotOpts); However, after some fudging around, I did not find a similar way of using axes ala: Theme.Call the nexttile function to create the axes objects ax1 and ax2.
