如何读取数据textread,例如通过xin textread( x_inlet.txt )我们可以把文件x_inlet.txt中的数据存储到数组xin中，且xin的维数和大小会自动与文件x_inlet.txt的相匹配。

如何设定坐标轴范围和坐标间距axis,set

例如 axis([0,7,0,12,-10,2])表示xyz坐标范围分别为0~7,0~12，-10~2，set(gca, XTick ,[0:1:7])表示x坐标范围为0~7，坐标间距为1.-How can we read the data textread, for example, through xin　 textread ( x_inlet.txt ) we can store the data in the file x_inlet.txt into the array xin, and the dimension and size of xin are automatically associated with the file x_inlet.txt match.

How to set the axis range and coordinate spacing axis, set

For example, axis ([0,7,0,12,10,2]) indicates that the xyz coordinate range is 0 ~ 7, 0 ~ 12,-10 ~ 2, set (gca,　XTick , [0: 1: 7]) indicates that the x coordinate range is 0 to 7 and the coordinate distance is 1.
