upy Tutorial ============ Webcast ------- There is a :doc:`Webcast` embedded into this documentation, presenting a talk on ``upy`` by me. Its auditory should match you, although I'm not sure how well I matched the auditory :-). Example Python Session ---------------------- Here is a small Python shell session:: Python 2.6.5 (r265:79063, Jul 18 2010, 12:14:53) [GCC 4.2.1 (Apple Inc. build 5659)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import upy >>> ua = upy.undarray(2, 0.1) >>> ub = upy.undarray(10, 0.05) >>> print ua, ub (2.00 +- 0.10) 10^0 (1.0000 +- 0.0051) 10^1 >>> print ub.printable(format='float') 10.000 +- 0.050 >>> print ua * ub (2.00 +- 0.11) 10^1 >>> print upy.cos(ua * ub) + ub (1.041 +- 0.092) 10^1 >>> uc = upy.undarray([[1, 2], [3, 4]], [[0.1, 0.5], [0.7, 2]]) >>> print uc [[(1.00 +- 0.10) 10^0 (2.00 +- 0.50) 10^0 ] [(3.00 +- 0.70) 10^0 (4.0 +- 2.0 ) 10^0 ]] >>> ^D Python-32(3414) malloc: *** error for object 0x239670: incorrect checksum for freed object - object was probably modified after being freed. *** set a breakpoint in malloc_error_break to debug Notice the nice error in the end. Can you reproduce this (on your machine)?
