Hi,
I have data sets as .csv with x and y coordinates. The data are correct and I plot them. However, I need to increase the X increment since the data are too much to be read by a machine. Does anybody know how can I increase the increment? Now, the X increment is 0.01 (inorganized, less or more) I need to plot the same thing with less number of points without reduce the accuracy too much. increment of let's say 0.5. What should I do?
Thanks

If you want to read every 5th point:
i = 1:5:length(x);
plot(x(i),y(i))
