[Numpy-discussion] Applying formula to all in an array which has value from previous

[Vishal Rana]

Hi,

For a numpy array:

array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])

I do some calculation with 0, 1... and get a value = 2.5, now use this value
to do the repeat the same calculation with next element for example...
2.5, 2 and get a value = 3.1
3.1, 3 and get a value = 4.2
4.2, 4 and get a value = 5.1
....
....     and get a value = 8.5
8.5, 9 and get a value = 9.8

So I should be getting a new array like array([0, 2.5, 3.1, 4.2, 5.1, .....
8.5,9.8])

Is it where numpy or scipy can help?

Thanks
Vishal
