One experiment carried out about 10 years ago by Ross Buck from Carnegie-Mellon University in Pennsylvania suggests that spontaneous facial expression is not a very good index of real emotional state. Buck and his colleagues tested the accuracy with which people could identify the emotions felt by another person. They presented one set of subjects with color slides involving a variety of emotionally-loaded visual stimuli – such as “scenic” slides (landscapes, etc), “maternal” slides (mothers and young children), disgusting slides (severe facial injuries and burns) and unusual slides (art objects). 点我阅读全文

【作业】第一章 MATLAB入门 第一章作业
1、 问题:1. 执行下列指令,观察其运算结果, 理解其意义:(2) [1 2; 3 4].0.1 0.2; 0.3 0.4log([1 10 100])(8)[a,b]=min([10 20;30 4])(9)abs([1 2;3 4]-pi)(10) [10 20;30 40]>=40,30;20 10find([10 20;30 40]>=[40,30;20 10])(12) [a,b]=find([10 20;30 40]>=[40,30;20 10]) (提示:a为行号,b为列号)(15) linspace(3,4,5)
评分规则: 【 答案提示:要简单写出MATLAB指令的意义。例如:[1 2; 3 4].[0.1 0.2; 0.3 0.4] 表示两个矩阵进行数组运算,即对应元素相乘的运算。(11) 答案表明:编址第2元素满足不等式(30>=20)和编址第4元素满足不等式(40>=10)(12) 答案表明:编址第2行第1列元素满足不等式(30>=20)和编址第2行第2列元素满足不等式(40>=10)
