plot a vector function with more than one step value in matlab

To plot a vector function with more than one step value in MATLAB, you can use the plot function along with the hold on command. Here's an example:

main.m
% Define the vector function
x = 0:0.1:10;
y1 = sin(x);
y2 = cos(x);
y3 = exp(-x);

% Plot the vector function
plot(x, y1, 'r');  % Plot y1 in red
hold on;  % Enable hold on
plot(x, y2, 'g');  % Plot y2 in green
plot(x, y3, 'b');  % Plot y3 in blue

% Add labels and a legend
xlabel('x-axis');
ylabel('y-axis');
legend('sin(x)', 'cos(x)', 'exp(-x)');

In the above example, we define three vector functions y1, y2, and y3 for different step values of x. Then, we use the plot function to plot each function with different colors. The hold on command allows us to plot multiple functions on the same figure without clearing the previous plots. Finally, we add the labels and a legend to make the plot more informative and understandable.

Note: The x values must have the same size as the y values for each function. Also, you can customize the plot by changing the line colors, line styles, markers, etc., according to your preference.
