Just for fun I downloaded and installed the NCAlgebra package. However upon running the NCTEST suite I got the following right off the bat:
SUMMARY OF TESTS
- 22 files tested.
- 1822 tests completed in 2.81575 seconds.
- 1819 succeeded.
- 3 failed.
SetCommutingOperators::AlreadyDefined: Symbols y and x were already defined commutative. Replacing existing rule.
TagUnset::norep: Assignment on y for NonCommutativeMultiplyPrivate
c___yx**NonCommutativeMultiplyPrivate
d___ not found.
TagUnset::norep: Assignment on x for NonCommutativeMultiplyPrivate
c___yx**NonCommutativeMultiplyPrivate
d___ not found.
Test #120 failed. Result:
True
differs from correct answer:
False
Test #121 failed. Result:
True
differs from correct answer:
False
SetCommutingOperators::AlreadyDefined: Symbols y and x were already defined commutative. Replacing existing rule.
TagUnset::norep: Assignment on y for NonCommutativeMultiplyPrivate
c___yx**NonCommutativeMultiplyPrivate
d___ not found.
General::stop: Further output of TagUnset::norep will be suppressed during this calculation.
Test #130 failed. Result:
True
differs from correct answer:
False
END NCTEST
EVEN IF ALL THE TESTS SUCCEEDED YOU SHOULD QUIT THE KERNEL
IN YOUR MATHEMATICA SESSION AND START OVER.
Is anyone on here familiar with this package? And if so am I getting something others see or not?
