What are the different types of error bars I can use in MATLAB?

MATLAB supports several types of error bars: standard deviation, standard error, confidence intervals (using `propagestandarderror`), and custom error values. You can also specify custom lower and upper bounds manually. The choice depends on the nature of your data and the information you want to convey. Using standard deviation indicates data spread, while standard error indicates the variability of the sample mean. Confidence intervals provide a range within which the true population parameter is likely to fall.
