matlab - How to solve a really nasty system of nonlinear equations -


i'm trying solve rather nasty system of equations consisting of 160 quadratic equations on 16 variables. know there tons of solutions (tons being @ least subvariety of dimension 6's worth) ones know aren't ones i'm interested in.

i tried using fsolve on matlab, fails when feed solution know works starting point (not time though, suspect not error in equation set, it's many equations handle reliably[mumble mumble... tolerance... mumble]). also, using normal solve function hilariously inadequate: if reduce system 20 quadratics, still takes quite awhile.

does know of computer algebra package or function can handle of magnitude?

thanks much!

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
