To find the derivative of a quadratic function in Matlab, you can use the polyder
function, which calculates the derivative of a polynomial.
Here is an example code block that shows how to find the derivative of the quadratic function f(x) = 3x^2 + 2x + 1

In this example, polyder
calculates the derivative of the quadratic function defined by the coefficients coefficients
, and returns a new set of coefficients derivative_coefficients
, which represents the derivative function. The polyval
function is then used to evaluate the derivative function at a specific value of x
, and the resulting derivative value is printed to the console.
