MATLAB: Is there an efficient method to remove leading underscores from a cell array of strings

Question

Given

a={'rose','_tulip_blue','lilac','_daisy'}

is there an efficient way of stripping the leading underscores to give

b={'rose','tulip_blue','lilac','daisy'}

I tried

strtok(a,'_')

but that gives

b={'rose','tulip','lilac','daisy'}

and misses the '_blue'. I would like to avoid looping through the strings one at a time if possible.

Answer 1

[b, c] = strtok( a, '_' )
b = strcat( b, c )

looks like it works.
