how to find a exact word in a string?

Hi I am trying to return the value that matches with a given word in a string...

str = 'talk talking people talk talking talk'

if this is my string and I am trying to return how many times 'talk' shows up in the string, what should I do?

this is my code so far but it also returns 'talking'... is there any other way to fix this?

find = strfind(str, 'talk')

length(regexp(str, '\<talk\>'))

if I assign a word to a variable and use regexp it does not work...can you help me with this?

str = 'talk talking people talk talking talk'
word1 = 'talk'
word2 = 'talking'

 ['\<' word1 '\>'] % in expression of sir Walters code

[Walter Roberson]

Madhan is correct, ['\<' word1 '\>'] as the pattern
