The function should have form:

[v] = sample_from_norrnal(m,EVecs,EVals)

Where m is the mean vector, EVecs is a matrix containing the eigenvectors of the covariance matrix and EVals is a vector containing the eigenvalues of the covariance matrix. (Hint: Generate a vector of samples from a unit normal distribution, scale the elements by sqrt(Evals) multiply by EVecs (to rotate the axes), then add the mean)
