SAMPLE PROGRAMMING PROJECT
Title: Find the derivative of a continuous function.
Background
To calculate the derivative of a function, f(x) at a point, x, we can use the approximation
dx
xfdxxf
xf )()(
)(
Specifications
Input values to the function are
function, f
point at which
)( xf
is desired, x
step size, dx
Return the following in the function
estimated value of the derivative of the function
Conduct three separate appropriate tests in a separate mfile to see if all parts of the function are
working.
Use comments appropriately in the function mfile.
Use comments, disp, and frprintf statements appropriately in the test mfile.
