transmitted seem
to be really slow in rate.
Is there any other way to compute SVD faster? FYI, I just need the V*
matrix within the result (U, S, V*).
Thanks,

Thank you all,
I went into /usr/lib/i386-linux-gnu/ and remove libvolk.so.0.0.0 with root.
Then I reinstalled gnuradio and it works now.

Dear all,
I had gnuradio-3.7.3 running normally. However, now everytime I run a flowgraph
in GRC, it stops and throws an error:

Dear all,
I want to save a matrix of integers into a file, similar to .mat file in
MATLAB. To be more specific, my desire block should receive a stream of
integers, convert it to MxN matrix and save this matrix so that I can get this
data for further process after the flow graph stops.
Could yo
Dear all,
I want to transmit an image over wireless link, so I need two blocks: + one for
reading grayscale image and giving out a bit stream+ the other one take a bit
stream as input and rebuild the image
Is there any completed toolbox containing blocks employing these functions? If
none, co

Deal all,
Does anyone update the Channel Coding (https://www.cgran.org/wiki/chancoding)
toolbox so that it can work in Gnuradio 3.7.0?
I did try to install this toolbox. The installation was done but it do not
appear in Gnuradio Companion interface.
Thanks,

Sorry, I didn't really get what you meant by "pipe the tagged stream
straight into the uhd sink".

. I found
that *stream tags* is the key solution to perform that.
My question is, how should I start to learn about* stream tags*, where can
I find tutorial of *stream tags*?
Thank you so much.
