hi,I am trying solve the simple problem:
 cvx_begin
 variable x(N)
 minimize(norm(x,1))
 subject to y==A*x
 cvx_end
and
N is about 3000
A is a 200×3000 matrix
then :

10.4100.1695.9e0011.4e+0032.2e+009
1.723168e+006 2.659794e+010 0:0:01 chol 
linsysolve: Schur complement matrix not positive definite switch to LU
factor. lu 11 7

1.916342e+006 3.692768e+011 0:0:07
** Too many tiny steps: restarting with the following iterate.**
 [X,y,Z] = infeaspt(blk,At,C,b,2,1e5);
lu 14 11  …………………………………………………………………………（Omit ）

2.377878e+019 2.024410e+014 0:1:12  sqlp stop: primal or dual is diverging, 1.3e+015
number of iterations = 65
Total CPU time (secs) = 72.15
CPU time per iteration = 1.11
termination code = 3
Status: Failed
Optimal value (cvx_optval): NaN
can anyone tell me what’s going on here？！
