MATLAB code to generate a bar chart with error bars

This is a MATLAB code that generates a bar chart with error bars and an average error line for a set of sample data.

This is a MATLAB code that generates a bar chart with error bars and an average error line for a set of sample data.

The first three lines clear the workspace, command window, and all figures.

The code then generates some sample data using the randn function, and computes the mean (mu) and standard deviation (sigma) of the data.

Next, the code computes the histogram of the data using the histcounts function, and calculates the bin centers and bin edges.

The code then calculates the errors as the standard deviation of the data and the average error between the mean and bin centers. It also creates a red dashed line to represent the average error.

Finally, the code creates a bar chart of the data with error bars, using the bar and errorbar functions. It also adds a legend and axis labels, and sets the font to Times New Roman with a font size of 14.
