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 -0.0313
0.1302 1.0000 0.0482 0.3843 0.2105 -0.2500 0.0803
0.0582 0.0482 1.0000 0.0481 0.3515 -0.0426 0.0574
0.0169 0.3843 0.0481 1.0000 -0.1819 -0.3554 -0.0020
0.0779 0.2105 0.3515 -0.1819 1.0000 0.0388 0.0186
0.0833 -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
