24 Jun 2013 LBFGSB (L-BFGS-B) mex wrapper Mex wrapper for lbfgsb v3.0 fortan library. L-bfgs-b solves box-constrained optimization. Author: Stephen Becker

Hi, Stephen
Thank you for the wrapper, which can work pretty well on my windows7 32bit.
But when compiling the wrapper on my desktop, win7 64bit, I met some problems.
I can compile the wrapper, but when running the examples, matlab will crash. I debug the problem. In the loop, when calling the lbfgsb.c at the first time, it is ok, but the second iteration, a breakpoint is triggered. When calling dcopy, matlab will crash down. I have no idea how can I solve the problem. My BLAS is 10.3.11. My matlab version is R2013a.
