[Matplotlib-users] quick numpy question
quick numpy-related question.
I want to use numpy.arange() to create multiple arrays, and then I want to
join these arrays (or individual elements) to the final array without
repeating existing elements (create a 'union' from 2 or more arrays or
individual elements).
example:
lev=np.arange(0,20,2)
# lev=(0,2,4,6,8,...,20)
lev1=np.arange(0,18,3)
#lev1=(0,3,6,9,12,15,18)
#I want something like...
lev3=lev1+lev2
#WITHOUT repeating elements (i.e., only one '12' in resulting array),
i.e., I want:
#lev3=(0,2,3,4,6,8,9,10,12,14,15,16,18,20)
#or, add just a unique element(s)
lev4=lev3+(50,60)
#so I would want lev4 to look like this:
#lev4=(0,2,3,4,6,8,9,10,12,14,15,16,18,20,50,60)
are these types of operations possible using numpy?
How can this be done?
Please help
Thanks,
P.Romero
