snoptmex - undefined function issue #10

Closed ghost closed 6 years ago

ghost commented 6 years ago

I'm trying to use SNOPT in Matlab, and found a problem that 'snoptmex' is undefined in Matlab. Although 'snoptmex' is used in several functions such as 'snscreen', there is no snoptmex.m(but only is snoptmex.f90) I think this is why Matlab can't treat 'snoptmex' as a defined function. How can I resolve this problem? Thank you for reading.

snoptmex is the name of the Matlab executable file. It should have the file extension: *.mex(maci64/a64/w64/w32) for macos/linux/windows 64/windows 32. It is not an m-file.

Do you have that file? If not, you can request a trial copy from https://ccom.ucsd.edu/~optimizers/downloads/

I got a trial version! Thank you for the help.

I just replied to your request right now. Your earlier request was approved on Oct 4 -- maybe it went into spam or something. If you don't get the email in the next few hours, let me know.

I just looked more closely -- your first email address was entered incorrectly (ia vs ai). Let me know if you have any more questions.
