Matlab Help

Two vectors are given: Use MATLAB to calculate the dot product u. v of the vectors in two ways: a) Define u as a row vector and v as a column vector, and then use matrix multiplication b) Use dot function. Write MATLAB code that will evaluate and plot the following functions: a) Y-5*cos(3) for 101 equally spaced points on the interval 0 x 1 b) y = 11,7 for equally spaced points on the interval-5 5. x 1+x
