I want to ask my user to input a shape:
h=input('What shape do you want?:');
if h==square;
disp(h)
But this never works, Matlab shows me the following error message: "'square' requires Signal Processing Toolbox."
Can someone help me find a way to make this work please :)

You need to add the 's' to the input argument list, and then use strcmp for the comparison.
Try this:
h=input('What shape do you want?:', 's');
if strcmp(h, 'square')
sprintf('SQUARE!')
end

If you can't use contains() like in my answer because your version of MATLAB is too old, then you can make this more robust by using strcmpi() instead of strcmp() and use strtrim() in case the user put any leading or trailing spaces on their response:
h = input('What shape do you want? ', 's');
if strcmpi(strtrim(h), 'square')
fprintf('SQUARE!\n')
end

Try using contains():
clc;
userResponse = input('What shape do you want? ', 's')
if contains(userResponse, 'square', 'IgnoreCase', true)
uiwait(helpdlg('You want a square.'));
else
message = sprintf('%s is an unrecognized response.\nTry again.', userResponse);
uiwait(warndlg(message));
end
