Plot data from a double class array
显示 更早的评论
Hi,
Is there a way to plot data directly from a double array? I have my x variables in column 1, and y variables in column 2. I am writing a program to do this with a large number of plots, so I would like a way to just graph a 360 x 2 double array.
Is there any way to do this? I know I can do x=array(:,1); y=array(:,2); plot(x,y)
but I would like to just do something like plot(array)

plot(array(:,1),array(:,2))
If you don't like that for some reason, you could do:
ac = mat2cell(array,size(array,1),[1 1]);
plot(ac{:})

You do have to break the value up to pass it to plot(). You could write your own wrapper for plot() that did the splitting for you to save you effort.
mplot = @(array,varargin) plot(array(:,1),array(:,2),varargin{:})
then
mplot(array)
or
mplot(array,'r.')
and so on.
