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.)

Finding the Nearest Orthonormal Matrix In some appoaches to photogrammetric problems (perhaps inspired by projective geometry), an estimate M of an orthonormal matrix R representing rotation is recovered. It is then desired to find the “nearest’’ orthonormal matrix. While this two step approach — first finding a “best fit’’ matrix without enforcing orthonormality,and then finding the nearest orthonormal matrix — is not to be recommended, it may be of interest to find a solution to this problem nevertheless.
