-gencode=arch=compute_21 is not a valid key

[aupilot]

There is (apparently) a bug in vl_compilenn.m

cudaArch = ...
sprintf('-gencode=arch=compute_%s,code=\"sm_%s,compute_%s\" ', ...
arch_code, arch_code, arch_code) ;

in my case (Mac, GeForce GTX 560 Ti) the variable arch_code gets "21". However, "compute_21" is not a valid flag, it must be "compute_20"

This workaround works for me:
cudaArch = ...
sprintf('-gencode=arch=compute_20,code=\"sm_21,compute_20\" ') ;

I have a similar problem. I need to change in the same way you suggest.

Duplicate to #143 . Fixed in the current version.
