Hi,
in the Jupyter-Notebook "DMC_Capacity.ipynb" from the lecture CC_GBC, i get the folowing hint:
This use of ``*`` has resulted in matrix multiplication.
Using ``*`` for matrix multiplication has been deprecated since CVXPY 1.1.
Use ``*`` for matrix-scalar and vector-scalar multiplication.
Use ``@`` for matrix-matrix and matrix-vector multiplication.
Use ``multiply`` for elementwise multiplication.
I think this commes from the following line of code:
objective = cp.Maximize(np.sum(Ptilde,axis=0)*px + cp.sum(cp.entr(P*px))/np.log(2.0))
and needs to be changed to:
objective = cp.Maximize(np.sum(Ptilde,axis=0)
@px + cp.sum(cp.entr(P
@px))/np.log(2.0))
Best regards
