plot middle and end of an array
显示 更早的评论
HI i want of plot the beginning and end of an array, leaving out the middle bit
something like . . . (here the comma doesn't work)
figure, plot(x(1:417,900:1000), y(1:417,900:1000))
is there an easy way to do this without splitting up the array?
thanks
Charlie

figure; plot(x([1:417,900:1000]), y([1:417,900:1000]))
You have to put your indices into an array, then you can use them as any other array of indices, irrespective of whether they are contiguous or not.

In addition to what Adam said, if you want to leave a "gap" between elements 417 and 900, add a NaN value. As a simpler example:
% The NaN at the end of x allows us to put a NaN in the middle
% of the array to be plotted, x(ind), using indexing
x = [1:10 NaN];
y = x.^2;
ind = [1:5 11 7:10];
plot(x(ind), y(ind), 'o-')
Note that the points (5, 25) and (7, 49) are not connected. If instead you'd done something like:
ind2 = [1:5 7:10];
plot(x(ind2), y(ind2), 'o-')
those two points would be connected.
