Barerrorbar() creates a bar plot with error bars. Although, not the first function to accomplish this task, barerrorbar() differs in that it directly calls the MATLAB functions bar() and errorbar() so that the options of both functions are preserved. For example:
x = 0.2*randn(3,4,100) + 1;
xMeans = mean(x,3);
xMeansL = repmat(3*0.2/10,3,4);
xMeansU = repmat(4*0.2/10,3,4);
barerrorbar({3:5,xMeans,'m'}, {repmat((3:5)',1,4),...
xMeans, xMeansL,xMeansU,'bx'});
