if I have 5 sentences (s1, s2, s3, s4, s5) and i put them all into one string (s) using:
s=[s1 ' ' s2 ' ' s3 ' ' s4 ' ' s5]
How would I go through all the words in each sentence to ascertain and display the most frequent word in ALL sentences?

I would use MAT2CELL to split the words in 's' into individual cells. Then I would use UNIQUE and HISTC to count repetitions.

regexp() with the 'split' option to break the string into words. Then you can unique() the resulting cell array, and examine the third output of unique() to determine how many times each value occurred.
