i have the student matlab with simulink and I am trying to code in the vector components such as V = [A*i + B*j + C*k]. When i type this the i hat and j hat components are automatically recognized as imaginary units however the k hat is not recognized and therefore i cannot compute my vector. Is there a way to code in so the k hat is recognized as a imaginary unit such as i hat and j hat?

i, j, k in vectors are not equivalent to complex numbers. These are basis vectors along x, y, and z-axis. What are you trying to do with this equation? Are you trying to plot something?

MATLAB does not support the i, j, k quaternion "complex" numbers. The i and j in MATLAB are strictly the ordinary imaginary numbers.
To use quaternions, unless you have special class code for this, typically you would just represent them as ordinary 4-tuples. E.g.,
q_1 = [MM;A;B;C]
q_2 = [NN,D,E,F];
Then if you want to add them it is simple addition:
q_sum = q_1 + q_2;
