create a plot with the shape of a triangle in matlab

To create a plot with the shape of a triangle in MATLAB, you can define the vertices of the triangle and then plot them using the plot() function. Here's an example:

main.m
% Define the vertices of the triangle
x = [0 1 2];
y = [0 1 0];

% Plot the triangle
plot(x, y);
97 chars
7 lines

This will create a triangle with vertices at (0,0), (1,1), and (2,0).

If you want to fill the triangle with color, you can use the fill() function instead of the plot() function:

main.m
% Define the vertices of the triangle
x = [0 1 2];
y = [0 1 0];

% Fill the triangle with color
fill(x, y, 'r');
113 chars
7 lines

This will fill the triangle with red color. You can replace 'r' with any other color code to change the color.
