I have a while loop running where I bring in a sentence on every loop
Sentence(i) = ('some string of words');
I can split the words and count using the unique() function but...
I want to keep adding to a table that contains each unique word and the number of times it repeats
so it looks like...
while
Sentence(i) = ('some string of words that changes each iteration');
Words = splitlines(Sentence(i))
PL = (Words== "");
Words(PL) = [];
AnalysisWords = strings(0);
for i = 1:length(Words)
AnalysisWords = [AnalysisWords ; split(Words(i))];
end
AnalysisWords = lower(AnalysisWords);
[words,N,idx] = unique(AnalysisWords);
end
Im not sure how to turn this into a running list

Use unique and histcI to count the number of times the string repeated.

Hi,
You can look at the answer here where unique and hist functions have been used.
Rather than using hist function, you can use a map container, where words are stored as keys and thei number of occurences is stored as values.
