I'm assuming what you're asking is how to get all the coefficients
stored in a single array. This is probably not going to happen
automatically for you using auto-managed ENVI widgets. At least
that's my guess - I just don't see how you could. I think your
solutions are going to be a) NOT auto-managing the widgets and writing
an event handler yourself (note that this is NOT the same as not using
ENVI widgets..you can still use wiget_param without the /auto_manage
keyword), or b) writing some code that puts the coefficients
individually stored in your 'out' structure into an array. Solution a
is probably more elegant and better in the long run, and solution b
is probably more of a "quick and dirty" fix.
Hope that helps,
Jeff
