QPSK调制程序代码，绝对能用，大家一起分享(QPSK)

产生常用的M序列，M序列是模拟以及仿真常用的序列。以及产生逆M序列。(M arrey)

偏最小二乘法PLS广泛应用于很多领域。这个程序包提供了一个函数，使用非线性迭代偏最小二乘法NIPALS算法，实现PLS回归。同时包含NIPALS算法的教程(PLS PLS is widely used in many areas. This package provides a function, use of non-linear iterative partial least squares algorithm NIPALS achieve PLS regression. NIPALS algorithm contains tutorials)

Edge detection result should be enhanced using linear method like Median filter to remove the garbage around the pupil to gain clear pupil to determine perfect centre. Get the centre of the pupil by counting the number of black pixels (zero value) of each column and row. Then get each row and column that has the maximum number of these black pixels. Then determine the center by simple calculation according to the image coordinate to set it correct on the image, consequently we can determine the radius of the pupil. Thus we can find the pupillary boundary (inner). A similar procedure is extended by using a coarse scale to locate the outer boundary (limbus) which can be apparent by using the mid-point algorithms of circle and ellipse.
