Q2: A. Set up a vector V with the elements 1, 2, 3, 4, 5. Use MATLAB array operations on The vector V to set up the following results: 1. 1/2, 1, 3/2, 2, 5/2 2. Return the number of elements in the vector V. B. Use the linspace function to create vectors identical to the following created with colon notation: x = -4:2 C. The following matrix is entered in MATLAB, use colon notation to write a single- line MATLAB command to multiply the second row by the third column and assign the result to the variable c. A=[3 2 1:0:0.5:1;linspace(6, 8, 3)]

Please follow the following code format and not coping other codes cuz it doesn't work THANK YOU!IN PYTHON: Given an n×n matrix A and n×1 right-hand side b, write a function that carries out q iterations of the Gauss elimination outer loop (without pivoting), where q is an integer between 1 and n, and returns the resulting augmented matrix with all below-diagonal elements transformed to zero in the left-most q columns. the code format:

Using C++ Using only these simpler vector methods Create a vector of at least 10 integers. Cout the vector with spaces in between the integers. Cout the vector backward. Using loops that traverse the elements, create a new vector with the elements arranged from high to low. Cout the new vector. Do not use iterators for this exercise, or any other advanced methods--only the ones listed below.   Hint: Use multiple vectors, including the copying of vectors. vector<int> grades1 = {45, 67, 88, 45, 23}; vector<int> grades2 = grades1;     May Only Use These Vector Methods:   size()                              // Returns the number of elements empty()                         // Returns a boolean True if the vector is empty   push_back(element)    // Adds an element to the back of the vector pop_back()                    // Removes the element at the back of the vector   front()                             // Returns the element at the front of the vector back()…

ASSIGNMENT: Working with Vectors Write a menu-driven program that will allow the user to run any of the following questions. Please put the functions headers in h file and the functions definitions in a .cpp file. 1. Write C++ code for a loop that simultaneously computes both the maximum and minimum element in a given vector. 2. Write a function double scalar_product(vector a, vector b) that computes the scalar product of two vectors. The scalar product of two vectors A[al, a2, a3) and B(bl, b2, b3} is another vector C given by C{c1, c2, c3} where cl = al * b1, c2 = a2 + b2, c3 = a3 + b3. 3. Write a function that computes the alternating sum of all elements in a vector. For example, if alternatingSum() is called with a vector containing 149 16 9 7 4 9 11 then it computes 1-4+9-16+9-7+4-9+11=-2 4. Write a procedure reverse that reverses the sequence of elements in a vector. For example, if reverse is called with a vector containing 1 49 16 9 7 4 9 11 then the vector is changed 11 9 4 7…

now the pros and cons of using arrays vs. vectors. Know how to build and use a 2d vector. Know what the "at" function does if you try to access memory beyond the bounds of the array.

2. Use a two-dimensional (double-subscripted) array to solve the following problem: A company has four salespeople who sell five different products. Let each salesperson represent a row of your array and each product a column. You now have a 4 x 5 array. Once a day, each salesperson submits a slip for each different type of product he or she sold. Each slip contains: The salesperson’s number (1 to 4) (use this to get row subscript) The product number (1 to 5) (use this to get column subscript) The total dollar value of that product sold that day Thus, each salesperson submits from 0 to 5 sales slips per day (0, if they made no sales that day; and 5, if they sold every product that day). Your program will read a file that contains the information from all of the sales slips for the last month. Read until EOF. The file is named "productSales.txt". You need to create this file with at least 10 entries. Remember that the first number is the salesperson, the second number is the product,…
