Matlab用imagesc函数画图时,一般将图像矩阵的起点(1,1) 画在左上角,如果该点代表的实际位置是物体的左下角,那么Matlab所画的看起来就是倒立的图像,因此需要翻转Y轴。 以下介绍几种方法可以实现这一功能: (1) axis ydirection axis xy : 默认顺序,y轴的值从下往上递增 axis ij : 反向,y轴的值从上往下递...
4.axis ydirection 其中ydirection为ij,即将原点放在坐标区的左上角。y值按从上到下的顺序逐渐增加。 ydirection的默认值为xy,即将原点放在左下角。y值按从下到上的顺序逐渐增加。 5.axis visibility 其中visibility为off,即关闭坐标区背景的显示。而坐标区中的绘图仍会显示。visibility的默认值为on,即显示坐标区...
imagesc(T,p,eta) which produces the follwing image: Now I want to flip the y-axis so that 50 is at the bottom and 250 is at the top. The Image should flip as well. Using 테마복사 eta=flipud(eta) T=[360 660] p=[64 250] p=fliplr[p] imagesc(T,p,eta) doesn't work...

②ezplot(f,[a,b]):在区间 a < x < b a<x<b a<x
imagesc(B); cb = colorbar; cb.Layout.Tile = 'east'; 图第一眼看上去没什么问题,但仔细看发现,它依旧是分别画的每张图,上图中的数字9与下图中的12依旧是一个颜色。同时标签只是与下面这张图是对应的。 接下来我们尝试使用caxis函数,让我们看下caxis的官方文档是怎么说的:设置当前坐标区的颜色图范围。
将y1与y2的曲线画到文件名为figure1和figure2的两个文件中 34 axis([0.5 1 -1 1]) 设定x轴范围为0.5～1,y轴范围为-1～1 35 clf Clear current figure. 36 imagesc(A) imagesc Scale data and display as image. 把矩阵A画成黑色小方格
