Is it possible to convert binary integers generated using a randi() to quaternary integers (0-3) by taking two bits from the source and combining them?

Solved it myself. It can be done easily by converting back to decimal from Galois Field, reshaping into n x 2 matrix and adding the columns.

Yes. B1*2 + B2

Thanks. I forgot to mention that I am converting the binary integers to Galois Field with m=1 for BCH coding. Now I want to convert the numbers to quaternary format for QPSK modulation.

If you need to, put the 4 possible results into a vector, and index the vector at B1*2 + B2 + 1
