How to remove values from a data set to make it a specific length?

2 views (last 30 days)
I will explain myself better:
If I have
xdata = [ 1 2 3 4 5 6 7 8 ]
ydata = [ 1 2 3 4 5 6 ]
if I want to plot(xdata,ydata) it will say that the vectors must be the same length and I cannot plot it. Instead of going to my specific data set and manually deleting values, I would like xdata to have the same length as ydata. Somehow deleting those values, making them = [ ], so that both of them have the same length.

If that's what you want to do
xdata = [ 1 2 3 4 5 6 7 8 ];
ydata = [ 1 2 3 4 5 6 ];
% n is the minimum of {number of elements in xdata, number of elements in ydata}
n = min(numel(xdata),numel(ydata));
% plot the first n elements of ydata vs the first n elements of xdata
plot(xdata(1:n),ydata(1:n))
