pcolor函数怎么用的，如何画伪彩色图？？？
% V$ D% C: m5 B8 ^pcolor（Ｘ，Ｙ，Ｃ）的Ｘ，Ｙ，Ｃ三个参数格式有什么要求，他们之间有什么关系？

可以help看看pcolor函数的介绍

youOK

找help粗暴简单

pcolor(C) draws a pseudocolor plot. The elements of C are linearly mapped to an index into the current colormap. The mapping from C to the current colormap is defined by colormap and caxis.

* v5 N, `, R" @; T+ tpcolor(X,Y,C) draws a pseudocolor plot of the elements of C at the locations specified by X and Y. The plot is a logically rectangular, two-dimensional grid with vertices at the points [X(i,j), Y(i,j)]. X and Y are vectors or matrices that specify the spacing of the grid lines. If X and Y are vectors, X corresponds to the columns of C and Y corresponds to the rows. If X and Y are matrices, they must be the same size as C.

pcolor(axes_handles,...) plots into the axes with handle axes_handle instead of the current axes (gca).

% M& X4 b3 X/ S9 a! kpcolor(C)画出一个伪彩色图。C的元素线性地对应到当前的颜色分配表中。这从C到当前颜色分配表的对应是由颜色分配表和指定坐标轴的颜色定义的。
