Hi Andy, this is python, so batteries included :) Use the "import" block to "import math".
then, in the vector source's value field: [ math.sin(x/(2*math.pi)/num_samples) for x in xrange(num_samples) ] alternatively, "import numpy" and numpy.sin(numpy.linspace(0, 2*numpy.pi, num_samples)) Best regards, Marcus On 12/26/2015 11:09 AM, Andreas Ladanyi wrote: > Hi Martin, >> You can create a lookup table for pretty much anything using a vector >> source, it'll accept Python structures as inputs through GRC. > i tested your suggestion and i am asking myself if there is an easy > way to get a lot of lookup table values in to the vector value field > of the vector source block. > > andy >> >> M >> >> On 20.12.2015 13:40, Andreas Ladanyi wrote: >>> Hi, >>> i want to create a file for example with a sine lookup table.
