【求助】关于integral X(t).vi 的疑问
这个vi应该是求x(t)的积分吧,那么输出的结果应该是函数x(t)与坐标轴围成的面积,但是我随便输入了个数组,可返回值并不是预想的面积,不知这是为什么?请高手指点!谢谢<img src="attachments/dvbbs/2006-4/20064141645138121.bmp" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2006-4/20064141645138121.bmp\');}" onmousewheel="return imgzoom(this);" alt="" />

<P>你这个节点没有用过,数学方面用得很少,具体的话可以看一下它的说明文件,应该有很清楚的!</P> 看一看你的起点坐标和终点坐标,有可能是那里的问题。 <P>谢谢两位斑竹。我仔细看了它的说明,它的算法如下:</P>
<P>D:\formula.jpg</P>
<P>我不知道这种算法的依据是什么,但感觉应该是一种优化的算法吧,dt越小越精确</P> 要压缩文件才能上传!不然上传上去下载不了的兄弟!
