add error bars to a matlab plot with multiple data sets in matlab

To add error bars to a MATLAB plot with multiple data sets, you can use the errorbar function. Here's an example code snippet to demonstrate how you can do this:

main.m
% Generate some sample data
x = 1:10;
y1 = sin(x);
y2 = cos(x);
errors1 = 0.2 * ones(size(x));
errors2 = 0.1 * ones(size(x));

% Plot the first dataset with error bars
errorbar(x, y1, errors1, '-o', 'DisplayName', 'sin(x)');
hold on

% Plot the second dataset with error bars
errorbar(x, y2, errors2, '-s', 'DisplayName', 'cos(x)');

% Add labels and legend
xlabel('X values');
ylabel('Y values');
title('Plot with Error Bars');
legend

% Add grid
grid on
456 chars
23 lines

In this code snippet, we generate two sample datasets y1 (sine function) and y2 (cosine function) along with their corresponding errors errors1 and errors2. We then use the errorbar function to plot these datasets with error bars. The -o and -s parameters specify the line styles for the data points. Finally, we add labels, legend, and grid to our plot.

You can customize the error bars appearance by providing additional arguments to the errorbar function.
