syntax:

>xyerrorbar(x,y,xerror,yerror,s)

variables:

y=array of ydata
xerror=array of errors for x
yerror=array of errors for y
s=string argument for plotting the datapoints, The errorbars are plotted in red and blue

errorbars are symmetrical, that means that the function plots [x-xerror x+xerror] and [y-yerror y+yerror].

x,y,xerror,yerror must all be arrays.
