You can use the ssbmod function with required input arguments which will do the complete single sideband amplitude modulation with lower sideband as default. To have a look at different examples on how to use the function, see the Mathworks documentation page here. To apply Hilbert transform on signal y, use hilbert function as hilbert(y). You can observe that the real part would be the original real data and the imaginary part is the actual Hilbert transform about the continuous-time analytic signal. You can look at the example on how to do it in the Mathworks Documentation page here.
