The xv16 = bit seems take longer than I expect...If the xv16 case was the first time sin was called for a symbolic variable, the time may include loading some code into memory, or other initialization. What happens if you do them in the reverse order?
Thanks, but I meant the conversion from double to vpa takes too long: an order of magnitude longer than computing sin.
I think its just overhead because of a rather horrid loop over all elements done in vpa.m: easily fixable, but I may want to do it with pytave.
