Matlab中的線圖

Question

如何在不使用衝浪的情況下進行矩陣的線圖（如A = rand（5））？

Answer 1

如果你想在2D情節分別繪製每一列，你只寫

plot(A) 

如果你想用線條3D繪圖，你可以寫：

[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.
