All above answers compares well, but if you need to use custom function for mapping, and you have numpy.ndarray, and you need to retain the shape of array.
WebWe shall discuss one-to-one functions in this section. Onto functions were introduced in section 5.2 and will be developed more in section 5.4.

WebFormula For Number Of Functions. 1. Number of possible functions. If a set A has m elements and set B has n elements, then the number of functions possible from A to B is n m. For example, if set A = {3, 4, 5}, B = {a, b}. The total number of possible functions from A to B = 2 3 = 8. 2.

The former has equal spacing on each side (it's a \mathrel, I think), while the latter has greater spacing on the right.

In this case, idempotent means that projecting twice is the same as projecting once.
