U mentioned about filter-design but calling those python functions only generates/loads input parameter when execution of flow graph starts (coefficients for filters). I am asking about the possibility to use these function for processing or any block in GRC that supports code writing? Both Simulin

Hi, Simulink have a block named "Matlab Function", in which user can write Matlab code and use it just like other simulink blocks,so does GRC have a smilar block which supports gnuradio commands/function (for which GRC blocks are not yet written ) or is such block planned in the future? Regards,
