问题描述：
如何用matlab求面积?
y=[0.04972,0.07812,0.13424,0.18009,0.21851,0.24797,0.26592,0.28132,0.29462,0.30413,0.31318];
x=[0.00005,0.00439,0.00996,0.015,0.02009,0.02502,0.03005,0.03504,0.04007,0.04505,0.05004];
y为压缩应力（Mpa）,x为压缩位移（mm）.数据是从excel表中抄下来的.压缩时每分钟3mm,0.1秒取1个数.上面取的x的11个数就是1秒内的压缩位移（从0-1秒）,y是对应的压缩应力.求x,y组成的这条曲线与x轴围成的面积.（可以把它看做一个一个的梯形累加而成的,用cumsum.给个具体的程序吧,我不会编程,还有这个只是1秒的数据,如何应用到1分钟?2分钟?）
