errbar - add vertical error bars on a 2D plot

Calling Sequence

errbar(x,y,em,ep)

Parameters

• x,y,em,ep : four matrices of the same size.

Description

errbar adds vertical error bars on a 2D plot. x and y have the same meaning as in plot2d. em(i,j) and ep(i,j) stands for the error interval on the value y(i,j): [y(i,j)-em(i,j),y(i,j)+ep(i,j)].

Examples

t=[0:0.1:2*%pi]';
y=[sin(t) cos(t)]; x=[t t];
plot2d(x,y)
errbar(x,y,0.05*ones(x),0.03*ones(x))
