Richard Zapor submitted a Comment to Problem 955. ismember: Enhanced Time Performance for 'rows' - Speed Scoring (90% savings)

Jean-Marie, the methodology of converting multiple column value words into a single value has limited but specific applications where value ranges are limited. In the case of DNA sequencing the values can be made numeric 0:3. For ranges up to 255 the width gets limited to stay under the 2^64, or 2^53 limit for double. This challenge was a demonstration of a method to improve performance for functions like ismember.

Two whole lines. Someone is slipping. I especially enjoyed the regexp implementation that created trailing spaces for the words using split. Line 2 will take much longer to digest.
