solve quadratic equation a*x^2+b*x+c=0 in matlab in matlab

To solve a quadratic equation of the form ax^2 + bx + c = 0 in MATLAB, you can use the built-in function roots. Here's an example:

main.m
% Coefficients of the quadratic equation
a = 1;
b = 2;
c = -3;

% Solve the quadratic equation
x = roots([a, b, c]);

% Display the solutions
disp(x);

11 lines

In this example, the roots function takes a vector of coefficients [a, b, c] as input and returns the roots of the equation as a vector. The solutions will be displayed in the command window.

Note that if the equation has complex roots, the roots function will return complex numbers as the roots.

Hope this helps!
