(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

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:...
