ploting error bars of matrix

i have a matrix A of 300*2 first colum is a time stamp and secornd colum is measurement. I have calculated the error of associated with measurement and named it error_data how can i plot the graph of matrix A with errorbars i.e the error_data. I am a rookie in matlab at the moment

Here is one approach:

M  = [1:20;  rand(1,20)]';

fun = @(M) [M(:,1)  M(:,2)  M(:,2)*sqrt(5E-11)];

R = fun(M);

figure(1)
errorbar(R(:,1), R(:,2), R(:,3))                    % ‘Regular’ Error Bar Plot
grid

figure(2)
plot(R(:,1), R(:,2), '-b')                          % Plot Blue Line Data
hold on
errorbar(R(:,1), R(:,2), R(:,3), '.r')              % Plot Red Error Bars
hold off
grid
