I am trying to generate a bar graph that also has standard error bars

and is grouped by the data from each row.

I have a matrix of mean values ('m') that is 5x3. The columns

corresond to times (0 min, 15 min, and 60 min in my case), and the

rows correspond to different anesthetics. There is also another 5x3

matix of the Standard Error values ('SE').

Using the 'bar' function I am able to plot the data from 'm' into 5

groups of 3 columns, but I can't label the groups with a character

string or add standard error bars. Can someone help me out here?

Maybe there's a different function I can use to make the bar graph.

Here's some sample data to work with:

% 5x3 Matrix of Mean Values

m =[ 100 200 110; 100 250 115; 100 300 150; 100 400 350; 100 325

200];

% 5x3 Matrix of Standard Error Values

SE = [10 10 7; 5 35 35; 9 14 23; 7 7 13; 4 11 24];

% This plots the data in a bar graph

bar(m)
