轴标签问题 [英] Axis labeling question

问题描述

通过运行以下我编写的matlab函数，图中的x轴和y轴互换.

The x-axis and y-axis are interchanged in the figure by running the following matlab function I wrote.

有人可以告诉我问题出在哪里还是帮助我解决它?预先感谢您的帮助.

Could anyone tell me where the problem is or help me fix it? Thanks in advance for any help.

function axislabeling(n)
x=1:1:n;
y=1:1:n;

z=zeros(n,n);

for i=1:n
    for j=1:n
        z(i,j)=i;
    end
end
surf(x,y,z(x,y))

xlabel('x-axis')
ylabel('y-axis')
zlabel('z-axis')

推荐答案

我怀疑问题不是不是轴标注错误，而是图形不是您期望的那样.原因是可以访问(行，列)matlab矩阵(即(y,x))，而不是根据需要访问(x,y).因此，当您设置z(i,j)=i时，您会得到错误的方向坡度.

I suspect the problem is not that the axes are mislabelled but that the graph is not what you expect. The reason is that matlab matrices are accessed (row, column) -- ie, (y,x) -- rather than (x,y) as you have it. So when you're setting z(i,j)=i you're getting the slope in the wrong direction.
