How do I use the strsplit function to split a sentence into a string of letters?

y = strsplit(sentence,{''},'CollapseDelimiters',true);

I need to find something to set as a delimiter that will split the sentence up into characters.

It is not very clear what exactly you want to achieve (you did not give any input and output examples), but here are some possibilities. To split a sentence into words:

regexp(sentence, '\s+', 'split')

To split the sentence into characters, ignoring the spaces:

regexp(sentence, '\S', 'match')

If you simple want every character in its own cell, including spaces, then this works:

num2cell(sentence)

[Zack Rabas]

that splits each word into a cell. I need to split each letter into a cell, I'm not sure how to do that

"I need to split each letter into a cell, I'm not sure how to do that"

That is what my second example does. It is not clear what you want to do with space though.

But WHY does it need to be a cell array? Is it homework where it requires it? Why not just leave it as a vector like I showed?

A sentence is ALREADY an array of individual characters.:

sentence = 'Hello World';
for k = 1 : length(sentence)
  disp(sentence(k))
end

You'll see

H
e
l
l
o

W
o
r
l
d

No need for strsplit() or cell arrays. Just use an index and treat it like any other vector.

Another option:

sentence = 'This is a sentence';
y = num2cell(sentence);                             % Cell Array Of Letters With Spaces
y_nospace = y(~strcmpi(y, ' '));                    % ... And Without Spaces
