Hello, I have a text file and I want to see how much 'Hi there!' word inside of it. How can I do it? Thank you.

What do you want to have happen if one of the occurrences is "PHi there!"? or "hi there!"?

Phi there is not meaningful and it is impossible to found in my text file. But it is a good point.

Did you try
fileChars = fileread(fileName);
locations = strfind(fileChars, 'Hi there!')
numLocations = numel(locations)

If you have "hi there" with lower case H, and you are searching for "Hi there!' with upper case H and with ! then the count should be 0.

data = fileread("content.txt")
pattern="hi there!"
substr_freq =count(data,pattern)
%substr_freq has your answer
