Hi,
I've got an array of irregularly spaced data points, like this:
* *
*
* *
* *
*
I'd like to resample them so that the signal between points is simply
the value at the previous point, like this:
**** *****
*****
**** *
********** *****************
****
I'd like the output to have regularly spaced data points. This means
that the exact times of the original data points will be lost, but
that's OK.
I've searched scipy.signal in vain (I'm not even sure what to call this
procedure, though I probably should). What's the best way to do this in
scipy?
Thanks,
