Hello
I want to convert some unsigned decimal numbers to a fixed point number
i was previously using the following but seem to be getting an error
Should this be working or am i missing a step
q = quantizer(12,14) % for a 12.4 fixed point number
binary_vector = dec2bin(some_Double_int)
bun2num(binary_vector,q)

You might try the command fi
For example, converting the value 1.5 to fixed-point signed, with wordlength 10 and fraction length 6, you type:
a = fi(1.5,1,10,6);
See more about this command in the documentation:
