gca是指你最近绘制的那个图像的句柄set(gca,'Position',[0011]);是指把figure('Position',[0-300size(cx1,2)size(cx1,1)]);这句绘制的图像的坐标轴改成0-1，0-1
(9)Position由位置向量[left,bottom,width,height]组成,决定坐标轴位置 (10)Tag定义本坐标轴的卷展栏,因为每一个对象都有自己唯一的识别码即tag,以方便findobj函数查找坐标轴句柄值。 (11)visible决定坐标轴是否可见 (12)set(gca,'xgrid','on')绘制X轴垂直网格线 set(gca,'gridlinestyle',':','linewidth',...

这也适用于图窗和坐标区的单位 - 始终先设置Units属性,然后再设置希望以这些单位解释其值的属性。例如, AI检测代码解析 f = figure('Units','characters','Position',[30 30 120 35]); 1. 另请参阅 findobj|gca|gcbo|gcf|gco|get

和其它语言一样，set对对象进行设置，h是前一个图像的句柄，get(h,'LineWidth')得到原图形的线宽。set(h,'LineWidth',4*get(h,'LineWidth'))即设置图形的线宽为原来的4倍。你
(16)H = findobj(ObjectHandles,属性名称,属性值);根据限定的对象列表找出与对象的属性名称和属性值匹配的对象句柄值(17)gcf返回当前Figure对象的句柄值gca返回当前axes对象的句柄值gco返回当前鼠标单击的句柄值,该对象可以是除root对象外的任意图形对象,并且Matlab会把当前图形对象的句柄值存放在Figure的CurrentObject...
