Hi,all.When I am using the cvx tools to solve the problem
something confusing happended.i.e,
for every observation value yi,the optimal vector xi is a zero vector.
Is there anyone who could tell me what’s wrong?Following is my codes for finding the optimal vector for y3,and C is a given 100x200 matrix.
minimize( norm(x,1) )
I'd appreciate it if you guys could help me out.Thanks again!
I think you want
You need == for an equality constraint. Using a single =, your d is a CVX expression, C*x, and has nothing to do with your d which was C(:,3).
Because your problem as incorrectly entered is unintentionally unconstrained, the zero vector is always optimal.
Thank you a lot.I have solved the problem above.
However,I am Now having big troubles,stuck in MOTION SEGMENTATION ALGORITHMS.
More specifically,motion segmentation refers to the problem of separating a video sequence into multiple spatiotemporal regions corresponding to different rigid-body motions.
Coding is some kind of art.That’s what I got these days.
