SDP,I want to know if my code is wrong，thanks

cvx_begin sdp
variable lemada nonnegative
variable u nonnegative
variable tao
maximize(tao)
subject to

[c0-(lemada)*c1-tao b0’+(lemada)*b1’;b0+(lemada)*b1 A0+(lemada)*A1]>=0;

cvx_end

You are missing u all 4 elements. And have the wrong sign for the 2nd term of he (1,1) element.

And you are missing the 2nd SDP altogether.

Thank you for your answer，Can you see if this is correct？

cvx_begin sdp
 variable lemada nonnegative
 variable u nonnegative
 variable tao
 maximize(tao)
    subject to
       [c0+(lemada+u)*c1-tao  b0'+(lemada+u)*b1';b0+(lemada+u)*b1 A0+(lemada+u)*A1]>=0;
        A0+lemada*A1>=0
cvx_end

It’s papers

That looks correct to me.

Thank you very much！
