Fmin

fmin(f, a, b)

f is a user defined function with single independent variable

a, b are scalars

Return both the minimum value and the location of the minimum value for function f in range [a,b]

Input

Output

f(x) => x^3 - 2*x - 5

fmin(f, 0, 2)

f(x) => x^3 - 2*x - 5

<f_min, x_min> = fmin(f, 0, 2)
