Assuming that the number of digits is always the same....
Method one: reshape and matrix multiply:
>> V = [16, 29, 0.599, 16, 30, 0.297, 16, 33, 0.178];
>> Z = [100,1,1]*reshape(V,3,[])
Z =
1629.599000000000 1630.297000000000 1633.178000000000
Method two: indexing:
>> Z = 100*V(1:3:end) + V(2:3:end) + V(3:3:end)
Z =
1629.599000000000 1630.297000000000 1633.178000000000
