最小二乘代码matlab

代码说明：

  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.)
