Dear John, 
My name is Emad and I am a Ph.D. student at the University f Malaya (Malaysia).
I would like to ask how to obtain the Co-state (Lagrange multiplier) in APM Matlab for optimal control problems.

Best Regards, 

John Hedengren

Lagrange multipliers are available from some solvers when DIAGLEVEL is set to 2 or above. The run directory will have a file apm_lam.txt that contains the Lagrange multipliers.
