Write MATLAB code. For input vector x, write a function to return vector y in which all the elements in vector x are duplicated. Example: If input x = [1 0 4], then y = [1 1 0 0 4 4]

For input vector x, write a function to check whether there exists at most 5 elements in x whose values are less than 7.

Write the code in python to define the function has_adjacent_repeats(mystr), which takes a string parameter and returns a boolean result.   - If mystr has at least one instance of adjacent characters being equal, return True   - Otherwise, return False Hint: You can iterate over the positive indices i for characters in mystr: 1, 2, 3, ...., len(mystr)-1 with a for loop. For each i, if the character at index i matches the character at index i - 1, return True. Otherwise, if no doubled character is found in the entire string, return False. For example: Test Result if not (has_adjacent_repeats("NOODLES") is True): print("error")   if not (has_adjacent_repeats("Bananas") is False): print("shwoopsie")   if not (has_adjacent_repeats("Hanoverr") is True): print("error")

Write a similarprogram to compare two vectors. we should make 6 test : same length the first is longer, the second is longer, equal, the first  greater , the second greater; try different symbols not only letters

Write the MATLAB commands that assign 33 and 4 to the variables a and b, respectively. Then, create a column vector W with the elements а! In(ab) Vb - a V(a + b)² – (b – a)? -a b where y! is the factorial of y, for which you should use a built-in MATLAB function, and In(x) is the natural logarithm of x. Finally, compute the average of the elements in W.

Write a function in matlab that takes a matrix with m rows and n columns and returns the sum of all of the odd numbers inside of that matrix.
