impropermsg = input('Enter the sentence : \n', 's');
function propermsg = changemsg(impropermsg)
propermsg = strcat(upper(impropermsg(1)),lower(impropermsg(2:end)));
end
% The user can input but nothing happens

You created a function that looks like it will do what you want but (at least in the code you posted) you never called the function.
You could just eliminate the 2nd and 4th lines of this code and you will have a simple two line script that does what you want (with the answer being in the propermsg string). If you want the result to be displayed, just take the semicolon off of the end of the propermsg = ... line.

Make a script called something like test.m, and put this into it:
impropermsg = input('Enter the sentence : \n', 's');
% Now call the function:
propermsg = changemsg(impropermsg);
fprintf('The result is "%s"\n', propermsg);
function propermsg = changemsg(impropermsg)
propermsg = strcat(upper(impropermsg(1)),lower(impropermsg(2:end)));
end

word='si'
new=replace(word,word(1),upper(word(1)))

That doesn't replace the rest with lower case like requested:
word='siUPPERCASE'
new=replace(word,word(1),upper(word(1)))
You'd need to add this line:
new = replace(new, word(2:end), lower(word(2:end)))

str = "test";
pat = lineBoundary("start")+lettersPattern(1);
new_str = replace(str,pat,(upper(extract(str,pat))))
