Hi, I'm trying to implement a test suite for a correlator and I'm having serious problems with my understanding of fi. The output of the fft stage is UFIX 36_0. I capture that in a matlab variable (say fft_out0). All I want to do is split that up into Re and Im parts at FIX 18_17. I'm finding this rather difficult to do in matlab (especially because simple bit operations such as & >> and representing numbers via 0x notation do not work).
If for example I try and convert the output from matlab fi(fft_out0,0,36,0) I still get a fractional number which baffles me. Is there a way to take this UFIX36_0, split into two FIX 18_17 and turn it into a complex number? Ross p.s. I'm using the unbus blocks to create the simulink output. I don't want to manually add gateways from every re_im block unless I really have to. (p.p.s I'm coming from scipy where this would be trivial hence the want to throw the toys out of the pram) -- Ross Williamson Research Scientist - Sub-mm Group California Institute of Technology 626-395-2647 (office) 312-504-3051 (Cell)
