hi . I have a equal constraint in GP as follow:
p1(t)*I1(t)==r1;
p2(t)*I2(t)==r2;
p3(t)*I3(t)==r3;
p4(t)*I4(t)==r4;
p5(t)*I5(t)==r5;
pb(t)==r6
r1+r2+r3+r4+r5+r6=r7;
r7==pl(t);
that p1(t), p2(t),p3(t),p4(t),p5(t),I1(t),I2(t),I3(t),I4(t),I5(t),r1,r2,r3,r4,r5,r6,r7,pb(t) are variables that defined and pl is a constant vector. but cvx showes error:
Disciplined convex programming error:
Invalid constraint: {log-convex} == {log-affine}

Error in == (line 12)
b = newcnstr( evalin( ‘caller’, ‘cvx_problem’, ‘[]’ ), x, y, ‘==’ );

Error in project (line 96)
r1+r2+r3+r4+r5+r6==r7
please help me , thanks.

When I use “<=”, it can be accepted by cvx, but “>=” is refused by CVX.
Disciplined convex programming error:
Invalid constraint: {log-convex} == {log-affine}
How should I change it to ensure that the use of “>=” can be accepted
Thanks again！
