拟合圆1

说明：  该过程利用了这样一个事实:在静态条件下，加速度计输出矢量的模量与重力加速度的模量相匹配。该校准模型结合了各轴的偏置和比例因子以及交叉轴的对称性 的因素。通过高斯-牛顿非线性优化计算参数。(The process takes advantage of the fact that the modulus of the accelerometer output vector matches the modulus of the gravitational acceleration under static conditions. The calibration model combines the offset and scale factors of each axis and the symmetry of the cross axis factors.)

同学录的设计，这是计算机网络的课程设计的题目。可以实现登陆、注册、上载图片、留言等功能。(website design, which is the computer network curriculum design topic. The landing can be achieved, registration, uploading pictures, voice mail capabilities.)

说明：  运用Matlab编写最小二乘法拟合程序，并指定标记符颜色或者是标记符（小圆圈、正方形、棱形、正五角星、正六角星和四个方向的三角形）周边线条的颜色。取值在上表。 在所有的能产生线条的命令中，参数LineSepc可以定义线条的下面三个属性：线型、标记符号、颜色进行设置。(The least squares fitting program is programmed by using MATLAB, and the color of the marker or the color of the lines around the marker (small circle, square, prism, pentagon, hexagonal star and triangle in four directions) is specified. Take the values in the table above. In all commands that generate lines, the parameter LineSepc defines the following three attributes of a line: line type, marker symbol, and color.)
