Thread Subject: How to use Matlab to plot mean and standard deviation of a data set?

How to use Matlab to plot mean and standard deviation of a data set please? I do not want to use "boxplot" because it is too complicated for my data display.

I just want to display a mean value with standard deviation. Basically, the plot should like a vertical line with a dot at the center denotes the mean value, and two short horizontal lines denote the standard devition. Any help will be greatly appreciate:-)


Thanks.

If i understood you i think it is easy.
Put your data in vector or columns. After that use the commands var() and std. Once you have it, just use plot command.
