如何在Matlab中绘制连续的彩色矢量场? [英] How to plot continuous colored vector field in Matlab?

问题描述

我有2个矩阵 A 和 B ，并且通过 quiver(A，B)我可以轻松地绘制矢量场.但是，有人知道如何在Matlab中以下列方式可视化矢量场吗(真的不知道这种绘图的名称)

I have 2 matrices A and B, and by quiver(A,B) I can easily plot a vector field. However, does anyone know how to visual vector field in the following way in Matlab?(don't really know the name of this kind of plot)

感谢您的帮助！

推荐答案

如果您正在寻找震级图(速度)，则:

If you are looking for a map of magnitude (velocities), then:

v = sqrt( A.^2 + B.^2 );
figure; imagesc( v ); colormap jet;colorbar; axis image;

或者，如果您想要像这样的示例那样在HSV颜色空间中编码幅度和方向的结果:

Alternatively, if you want results that encode magnitude and direction in HSV color space like this example:

您可以找到此代码有用.
