(5pts) Vectorize this code! Write one assignment statement that will accomplish exactly the same thing as the give code (assume that the variable mat has been initialized).

[r, c] = size(mat);

for i = 1:r

for j = 1:c

mat(i,j) = 2*mat(i,j)^2 – 6*mat(i,j)+1;

end

end

let us create a variable for a row vector a = [1, 4, 1, 3, 2, 5, 0] and calculate the mean value of its elements using the Matlab function ‘mean’ and store this value in variable aMean. Fig. 1 gives the Matlab code to do this. a = [1, 4, 1, 3, 2, 5, 0]; aMean = mean(a); Figure 1: Matlab code – row vector and mean of its elements. Let us now construct a row vector b that...

For this assignment, you need to write a parallel program in C++ using OpenMP for vector addition. Assume A, B, C are three vectors of equal length. The program will add the corresponding elements of vectors A and B and will store the sum in the corresponding elements in vector C (in other words C[i] = A[i] + B[i]). Every thread should execute an approximately equal number of loop iterations. The only OpenMP directive you are allowed to use is:...

For this lab assignment you will need to write some code and create some graphs. You may use excel to create your graphs, or other language of your choice. Your data needs to demonstrate the experimental running time for Selection Sort (code in book), Merge Sort (code in book), and the Arrays.sort() method. Here is a basic outline of how you need to code this assignment. 1) Create several arrays of size 100, 1000, 10000, 100000, 1000000, … (you need...

MATLAB CODE: Matlab’s polyder() and polyint() functions return the derivative and integral of a polynomial, respectively. For example, polyder([4 -2 3 7 -5]) yields [16 -6 6 7] in other words: d/dx{4x4−2x3 +3x2+7x−5} = 16x3−6x2 +6x+7and,polyint([16 -6 6 7]) yields [4 -2 3 7 0] note the zero at the end. in other words:∫(16x3-6x2+6x+7)=4x4–2x3+ 3x2+7x+? where C = 0 As seen above, the constant of integration is always assumed to be zero when using polyint().While polyint() is available, using your...
