make a bar graph in matlab

To create a bar graph in MATLAB, you can use the bar function. The bar function takes in two vectors of equal length, one for the x-axis values and one for the heights of the bars. Here is a simple example:

main.m
% Create some sample data
x = [1, 2, 3, 4, 5];
y = [10, 7, 5, 3, 8];

% Create the bar graph
bar(x, y);

% Add labels and title
xlabel('X Values')
ylabel('Bar Height')
title('A Simple Bar Graph')
196 chars
12 lines

This will create a basic bar graph with the sample data provided. You can customize the appearance of the graph by adjusting properties such as color and width of the bars, as well as font size and style of the labels and title.
