Q3: Write a matlab program call matq3.m that returns the plot of the 2- D space defined by the following equation: (-xsin(x) cos (x) - 2π ≤ x < 0 x = 2π Label the x-axis and y-axis and z-axis and title to the curve. y

Using a for-loop in Matlab for the given vectors V=[10, 1, 4, 10, 8]; W=[10, 4, 10, 3, 5]; a) Write a program (using for-loop) that calculates the dot-product, C=(V-W).W b) What is the value of C? Choices 214 |-9 |-36 |-13

IN PYTHON I want a code in python and no need to post work on paper Iwant a screenshot of the code A tridiagonal matrix is one where the only nonzero elements are the ones on the main diagonal and the ones immediately above and below it.Write a function that solves a linear system whose coefficient matrix is tridiag- onal. In this case, Gauss elimination can be made much more efficient because most elements are already zero and don't need to be modified or added. As an example, consider a linear system Ax = b with 100,000 unknowns and the same number of equations. The coefficient matrix A is tridiagonal, with all elements on the main diagonal equal to 3 and all elements on the diagonals above and below it equal to 1. The vector of constant terms b contains all ones, except that the first and last elements are zero. You can use td to find that x1= −0.10557. The following code format should help: def td(l, m, u, b):   '''Solve a linear system Ax = b where A is tridiagonal      Inputs: l,…

Initialize a vector v1 with the following values: 0 23 -7 8 -22 3 14 Write a MATLAB program from the values in v1. The vector v2 should contain the values in v1 transformed as follows: that uses a for-loop and if-statements to make a new vector v2 multiply each positive even element in v1 by 3, multiply each positive odd element of v1 by -2, and change the sign of the negative elements in v1. Then, output the new vector to the command window as follows: The new vector is: -46 7 24 22 -6 42 Also, compute and output the mean of the values in the new vector: The mean of the new vector is: xxxx Above, xxxx is the mean of the values in the new vector with 1 decimal place.
