matlab绘制矩阵色块图

本博客摘自天津科技大学谢中华一书，

       在R语言中有根据矩阵绘制色块图的程序，可以用于绘制相关系数矩阵图，用丰富的颜色和形状形象的展示矩阵元素值的大小。今天介绍的是如何用matlab绘制矩阵色块图。

1、绘制网格线，网格中显示矩阵元素，显示黑色文字。

 x = [1.0000    0.1302    0.0582    0.0169    0.0779    0.0833   -0.03130.1302    1.0000    0.0482    0.3843    0.2105   -0.2500    0.08030.0582    0.0482    1.0000    0.0481    0.3515   -0.0426    0.05740.0169    0.3843    0.0481    1.0000   -0.1819   -0.3554   -0.00200.0779    0.2105    0.3515   -0.1819    1.0000    0.0388    0.01860.0833   -0.2500   -0.0426   -0.3554    0.0388    1.0000   -0.1853-0.0313    0.0803    0.0574   -0.0020    0.0186   -0.1853    1.0000];
XVarNames = {'Sleep','Age','Sex','Rel','Psy','Ner','Cha'};
matrixplot(x,'FillStyle','nofill','XVarNames',XVarNames,'YVarNames',XVarNames);

效果图如下：

2、根据矩阵元素值自动设置文字颜色。

 x = [1.0000    0.1302    0.0582    0.0169    0.0779    0.0833   -0.03130.1302    1.0000    0.0482    0.3843    0.2105   -0.2500    0.08030.0582    0.0482    1.0000    0.0481    0.3515   -0.0426    0.05740.0169    0.3843    0.0481    1.0000   -0.1819   -0.3554   -0.00200.0779    0.2105    0.3515   -0.1819    1.0000    0.0388    0.01860.0833   -0.2500   -0.0426   -0.3554    0.0388    1.0000   -0.1853-0.0313    0.0803    0.0574   -0.0020    0.0186   -0.1853    1.0000];
XVarNames = {'Sleep','Age','Sex','Rel','Psy','Ner','Cha'};
matrixplot(x,'FillStyle','nofill','XVarNames',XVarNames,'YVarNames',XVarNames,'TextColor','Auto','ColorBar','on');

效果图如下：

3、绘制实值矩阵各元素对应的色块，通过不同的“参数/参数值”控制色块的形状、大小、颜色等属性。
方形色块，充满方格，灰白色字体。

 x = [1.0000    0.1302    0.0582    0.0169    0.0779    0.0833   -0.03130.1302    1.0000    0.0482    0.3843    0.2105   -0.2500    0.08030.0582    0.0482    1.0000    0.0481    0.3515   -0.0426    0.05740.0169    0.3843    0.0481    1.0000   -0.1819   -0.3554   -0.00200.0779    0.2105    0.3515   -0.1819    1.0000    0.0388    0.01860.0833   -0.2500   -0.0426   -0.3554    0.0388    1.0000   -0.1853-0.0313    0.0803    0.0574   -0.0020    0.0186   -0.1853    1.0000];
XVarNames = {'Sleep','Age','Sex','Rel','Psy','Ner','Cha'};
matrixplot(x,'XVarNames',XVarNames,'YVarNames',XVarNames,'TextColor',[0.6,0.6,0.6],'ColorBar','on');

效果图如下：
