plot 2d from data in matlab

To plot a 2D graph from data in MATLAB, you can use the "plot" function.

Here is an example code that demonstrates how to plot a simple 2D graph using data points:

main.m
% Define x and y data points
x = [1, 2, 3, 4, 5];
y = [10, 20, 15, 25, 30];

% plot the graph
plot(x, y)

% Add labels and title
xlabel('x-axis')
ylabel('y-axis')
title('2D Graph')

% Add grid lines
grid on

% Display the graph
228 chars
17 lines

In this example, we have defined two vectors, x and y, which represent the x and y coordinates of the data points, respectively. The plot function is then used to plot the graph using these data points.

We can also add labels to the x and y axes using the xlabel and ylabel functions, respectively. The title function is used to add a title to the graph. Additionally, the grid on command is used to display grid lines on the graph for better visualization.

To display the graph, you can either run the code in the MATLAB editor or save the code in an .m file and run it.
