Hi! numpy renamed the *function* abs to absolute. Most functions like mean, min, max, average, ... have an equivalent array *method*.
Why is absolute left out ? I think it should be added .
We've got __abs__ :-)
Furthermore, looking at some line of code that have multiple calls to absolute [ like f(absolute(a), absolute(b), absolute(c)) ] I think "some people" might prefer less typing and less reading, like f( a.abs(), b.abs(), c.abs() ).
One could even consider not requiring the "function call" parenthesis '()' at all - but I don't know about further implications that might have.
eh, no. things that return new arrays should be functions. (As opposed to views of existing arrays, like a.T)
PS: is there any performace hit in using the built-in abs function ?
Shouldn't be: abs(x) looks for the x.__abs__() method (which arrays have). -- |>|\/|< /--------------------------------------------------------------------------\ |David M. Cooke http://arbutus.physics.mcmaster.ca/dmc/ |cookedm@physics.mcmaster.ca
