how to plot sum of squared error in bar figure as group with 2 metrics in matlab

To plot the sum of squared error as a bar figure with two metrics in MATLAB, you can follow these steps:

1. Calculate the sum of squared error for each metric.
2. Create a bar graph with two groups, one for each metric.
3. Label the x-axis with the metric names and the y-axis with the sum of squared error values.
4. Add a legend to identify which group corresponds to which metric.

Here is an example code to help you understand the process:

main.m
% Example data
metric1_error = [4, 8, 5];
metric2_error = [6, 2, 7];
metric_names = {'Metric 1', 'Metric 2', 'Metric 3'};

% Calculate the sum of squared error
sse_metric1 = sum(metric1_error .^ 2);
sse_metric2 = sum(metric2_error .^ 2);

% Create a bar graph with two groups
sse_values = [sse_metric1, sse_metric2];
bar(sse_values)

% Label the x-axis
xticks(1:length(metric_names))
xticklabels(metric_names)
xlabel('Metrics')

% Label the y-axis
ylabel('Sum of Squared Error')

% Add a legend
legend('Metric 1', 'Metric 2')

You can replace metric1_error, metric2_error, and metric_names with your own data. The code will calculate the sum of squared error for each metric and plot them as bars in a group.

Make sure to adjust the code according to your specific requirements, such as changing data and customizing the plot appearance.
