multiple colored plots of a function in matlab

To create multiple colored plots of a function in MATLAB, you can use the plot function in conjunction with specifying different line styles or colors for each plot. Here's an example:

main.m
x = linspace(-5, 5, 100);  % create x values
y1 = sin(x);               % compute y values for function 1
y2 = cos(x);               % compute y values for function 2

% plot function 1 with red color
plot(x, y1, 'r', 'LineWidth', 2);
hold on;  % enable the hold state

% plot function 2 with blue color
plot(x, y2, 'b--', 'LineWidth', 2);

hold off; % disable the hold state
376 chars
13 lines

In this example, the plot function is used twice to create two plots, each with a different line style and color. The first plot is created with a solid red line ('r'), and the second plot is created with a dashed blue line ('b--'). The 'LineWidth' property can be used to specify the width of the lines.

The hold on command is used to enable the hold state, which allows subsequent plots to be overlaid on top of existing plots. The hold off command is used to disable the hold state and restore the default behavior of replacing existing plots.

By specifying different line styles and colors, you can create multiple colored plots of a function in MATLAB.
