MATLAB: How many zeros do I have before a specific sting variable

cell

Dear all
I have

' b1'
' b1'
' b1'
' b1'
'b1'
' b1'
[0]
[0]
[0]
'b1'
' b1'}
I have this cell vector. This vector has a characteristic. Immediately after the first zeros the letter 'b1' begins. So I would like to count the zeros before the first 'b1' that starts to appear in this vector. In this case I have 39 zeros. Is it possible to calculate this number using a Matlab code?
thanks

  • yourzeros = find(cellfun(@ischar,A),1,'first')-1;
