>> S = '21.5VgDC_0.05000V_VgAC_50M-150M30ms47GV1';
>> C = regexp(S,'\d+\.?\d*','match');
>> C{:}
ans = 21.5
ans = 0.05000
ans = 50
ans = 150
ans = 30
ans = 47
ans = 1

In the first one everything is optional, so it matches the empty pattern too.
The second one does require at least one digit. However it does not support digits followed by a decimal point with no digits after

C = regexp(S,'[-+]?\d+\.?\d*','match');
