plot a parabola in matlab

To plot a parabolic curve in Matlab, we first need to define the equation of the parabola. For a parabola of the following form:

main.m
y = a*x^2 + b*x + c

where a, b, and c are constants, we can generate the x and y values for the curve using the following code snippet:

main.m
% Define the constants for the parabola
a = 1;
b = 2;
c = 1;

% Define the range of x values to plot
x = -10:0.1:10;

% Calculate the corresponding y values for the parabolic curve
y = a*x.^2 + b*x + c;

% Plot the parabolic curve
plot(x, y);
xlabel('x');
ylabel('y');
title('Parabolic Curve');

In this example, the a, b, and c values are set to 1, 2, and 1 respectively. The code then generates a range of x values from -10 to 10 in steps of 0.1. The corresponding y values for the parabolic curve are calculated using the equation y = a*x^2 + b*x + c. Finally, the plot function is used to plot the parabolic curve using x and y. The xlabel, ylabel, and title functions are used to label the axes and title of the plot.
