Hi, I have the following CVX code that I am running with a matrix less than 10,000 x 10,000 and a respective size vector. When running, it calls for SDPT3 to solve but it takes ~40 minutes to run. My understanding is it should not take a long computational time.
Am I applying the equation wrong?
cvx_begin
cvx_solver
variable x(n)minimize norm((A_matrixAx-b_vectorA),2)+norm((A_matrixDx-b_vectorD),2)
subject to
cvx_end
The information given by CVX is as follows:
Calling SDPT3 4.0: 15604 variables, 9925 equality constraints
For improved efficiency, SDPT3 is solving the dual problem.
------------------------------------------------------------
num. of constraints = 9925
dim. of socp var = 15604, num. of socp blk = 2
