how to plot fitness function values as y-axes and generation number as x-axes in matlab

To plot fitness function values as the y-axis and generation number as the x-axis in MATLAB, you can use the plot function. Assuming you have the fitness function values stored in a vector called fitness and the generation numbers in a vector called generation, you can plot the graph using the following code:

main.m
% Define fitness values and generation numbers
fitness = [10, 8, 6, 5, 2, 4];
generation = [1, 2, 3, 4, 5, 6];

% Plot Fitness vs Generation
plot(generation, fitness)

% Add labels and title
xlabel('Generation Number')
ylabel('Fitness Function Value')
title('Fitness Function Values vs Generation Number')
306 chars
12 lines

This code will create a graph with the generation number on the x-axis and fitness function values on the y-axis. The plot function is used to create the line plot, and the xlabel, ylabel, and title functions are used to add labels and a title to the graph.

Make sure to replace the fitness and generation values with your actual data.

Note: If your fitness function values and generation numbers are not the same lengths, MATLAB will throw an error. Make sure the vectors have the same length or handle the error appropriately.

You can customize the plot further by adding gridlines, legends, markers, changing line styles, etc. Refer to MATLAB's documentation for more information on customizing plots: MATLAB Plotting Documentation.
