Function 'subsindex' is not defined for values of class 'phased.Ph​aseCodedWa​veform'.

I have received the following error

Function 'subsindex' is not defined for values of class 'phased.PhaseCodedWaveform'.

Error in Untitled6 (line 32)

bwrmss = bandwidth(h)/sqrt(12);

in my this part of whole code:

h = phased.PhaseCodedWaveform;
h.SampleRate = 100000000;
h.Code = 'Barker';
h.ChipWidth = 2e-08;
h.NumChips = 13;
h.PRF = 50000;
h.NumPulses = 1;

sig = h();
Nr = length(sig)
bwrmss = bandwidth(h)/sqrt(12);
rngrms = c/bwrmss;

It was working fine few hours ago. Then , i don't know what happened. After working on other codes, when i come back to this, this is now giving error.

Please help!

You probably have accidentally named a variable bandwidth and that is interfering with using bandwidth as a function.
