i have a simple array with floating values
array([ 0. , 0.2, 0.4, 0.6, 0.8])
what i need to do is change each index into another dimension with 3 indices. hmm, kind of confusing, an example will explain better
b = array(zip(a,a,a)) print b
array([[ 0. , 0. , 0. ], [ 0.2, 0.2, 0.2], [ 0.4, 0.4, 0.4], [ 0.6, 0.6, 0.6], [ 0.8, 0.8, 0.8]])
ok, this does the job, but once i start using large arrays, the back-n-forth conversion between arrays and python lists is costing me quite a bit. is there a way i can reshape the array this way without the call to python's 'zip'? (no, 'map' doesn't count either)
i've tried much fooling with NewAxis, resize, and friends. but either i haven't stumbled upon the correct combination or i'm not trying the correct tools. i'd like to keep this as quick as possible, so hopefully it can be done without anything too elaborate.
(doh, sorry for the previous distutils related post... hit the wrong mailing list)
