Gaphics
- 我是一名大学的学生，我没有做过很复杂的编程练习，这也是我第一次上传源程序，这次上传的是我做计算机图形学的练习时在WIN-TC环境下所编的一些程序，其中有二维图形的基本变换（平移，旋转，错切，放缩，对称）的动画演示、三维图在二维平面上的消隐图的显示、线条的裁减、抛物线的绘制以及B样条曲线的绘制，程序中有详细的注释，希望对学生朋友们能够有所帮助。-I was a university student, I had not done a very complex programming exercis

Close3B
- 采用拟三对角矩阵反算出过一定点（大于等于3个）的控制顶点，再由这些控制顶点计算出3次B样条曲线，由于曲线封闭的，所以无需引入边界条件即可求得曲线。-Used to be anti-tridiagonal matrix calculated over a certain point (greater than or equal to 3) of the control points and then calculate the control points of these 3 B-spline
EllipseFitByTaubin
- This is a fast non-iterative ellipse fit, and among fast non-iterative ellipse fits this is the most accurate and robust. It takes the xy-coordinates of data points, and returns the coefficients of the equation of the ellipse: ax^2 + bxy +

convolve2
- CONVOLVE2可以用于任何CONV2使用，采取同样的参数并返回一个小的公差范围内同样结果。加速计算是通过使用面膜中的奇异值分解，表示为外产品总结一下。这些都可以有效地计算与行和列向量的卷积。 CONV2是用来从事这项运动。 可分面具是一个特殊情况，并受CONVOLVE2处理多达FILTER2一样。许多不属于其他口罩可分低等级（如Gabor函数口罩），并更有效地处理CONVOLVE2。 该功能也将计算出降秩逼近一个给定的面具如果需要的话，将使用此是否会加速计算。一个额外
