Matlab中的线图

Question

如何在不使用冲浪的情况下绘制A = rand（5）等矩阵的线图？

Answer 1

如果要在2D绘图中单独绘制每一列，只需编写

即可

plot(A)

如果你想用线条制作3D图，你可以写：

[xx,yy] = ndgrid(1:6,1:5);
A = [A;NaN(1,size(A,2))]; %# add NaNs so that the lines will be plotted separately
plot3(xx(:),yy(:),A(:)) %# use plot3(xx(:),yy(:),A(:),'.') if you want to plot dots instead of lines.
