how to set the range of the fitness function values at y-axes in matlab

To set the range of the fitness function values on the y-axis in MATLAB, you can use the ylim function. This function allows you to manually specify the minimum and maximum values for the y-axis in a plot.

Here is an example of how to use the ylim function to set the range of the fitness function values:

main.m
% Generate some example fitness function values
fitness_values = [1, 2, 3, 4, 5];

% Plot the fitness function values
plot(fitness_values)

% Set the range of the y-axis to be between 0 and 10
ylim([0, 10])
207 chars
9 lines

In this example, the ylim([0, 10]) line of code sets the range of the y-axis to be between 0 and 10. You can adjust the range to suit your needs by modifying the values in the ylim function call.

Note that the ylim function should be called after the plot function, as it affects the existing plot. If you call ylim before plot, the range may not be set correctly.

By using the ylim function, you can define the desired range of the fitness function values on the y-axis in MATLAB plots.
