To obtain minimum value of a function without using derivatives, use methods like bisection, golden section search, or simulated annealing.

• Bisection method involves repeatedly dividing the interval in half and checking which half contains the minimum value.

• Golden section search is similar to bisection but uses a fixed ratio to divide the interval.

• Simulated annealing is a probabilistic method that randomly explores the

To define 3D array in MATLAB or Python, use array indexing. To obtain maximum from matrix elements, use max() function.

• In MATLAB, use array indexing with three dimensions: A(x,y,z)

• In Python, use numpy library to create 3D array: np.array([[[1,2],[3,4]],[[5,6],[7,8]]])

• To obtain maximum from matrix elements, use max() function: max(A)

• In Python, use np.max() function to obtain maximum from matrix elements

To get the median of a data sequence, sort the data and find the middle value.

• Sort the data sequence in ascending or descending order

• If the sequence has an odd number of values, the median is the middle value

• If the sequence has an even number of values, the median is the average of the two middle values

• Example: For the sequence [3, 1, 4, 2, 5], sort it to [1, 2, 3, 4, 5] and the median is 3

• Example: For the sequence [3,...read more
