$\huge\purple {\mathfrak{Bonjour Mate!}}$

My program requires a user to enter a 3 dimensional double vector v and a 3 x 3 double matrix M and the program will print out the matrix/vector product Mv. However I'm not getting a vector as my output, I'm getting a scalar. I'm not sure why, I've defined my output as a vector.
