## how to use results of NPL ?...

Dear friends,

How can I use the results of NPLSolve, in the next steps without redefining the results (see bold written lines)? Thanks for help.

> NLPSolve(residuals, initialpoint = {t21 = 10, vol1 = 5, vol2 = 5, clearance = 150});
print(`output redirected...`); # input placeholder
[51.7896105965666678, [t21 = 18.2125533155585906, vol1 = 7.88918815803283202,

vol2 = 5.44188808553054315, clearance = 171.037242037501159]]

## thanks...
