Matlab画平滑曲线的两种方法（ 拟合或插值后再用plot即可） 自然状态下，用plot画的是折线，而不是平滑曲线。有两种方法可以画平滑曲线，第一种是拟合的方法，第二种是用spcrv，其实原理应该都一样就是插值。下面是源程序。(You can then use the plot) Natural state, with the plot is a line drawing, instead of a smooth curve. There are two ways to draw a smooth curve, the first one is the fitting method, and the second is to use spcrv, in fact, the same principle should be that the interpolation. Here is the source.)
