function result = mvop(matrix, vector, op)
%result = MVOP(matrix, vector, op)
%
%Apply a binary array operation on a matrix-vector pair
%
%Input:
%  MATRIX - first argument (matrix M x N)
%  VECTOR - second argument (vector M x 1 or 1 x N)
%  OP     - binary array operation
%
%Output:
%  RESULT - result of the operation applied to MATRIX and expanded VECTOR
%
%Example:
%  matrix = reshape(1:12, 4, 3)'
%  mvop(matrix, [1 2 3 4], '-')
%  mvop(matrix, [1; 2; 3], './')
