Consider the following function: a. Perform 3 iterations of golden section search method by hand to find the minimum value of this function. Start from interval-2 x 1 . b. Perform 3 iterations using parabolic interpolation method to find the minimum value of this function. Use initial points of xi =-2=-1,x-1 . Use fminbnd function in MATLAB to find the minimum value of the given function in range of -23xsl c. Consider the following function: a.
