How to get input from user without asking to press enter at MATLAB prompt?

Best Answer

The ability to take input from user without asking to press enter is not directly available through any of the features in any of the MATLAB releases.

As a possible workaround, WAITFORBUTTONPRESS and 'CurrentCharacter' can be used. Following is an illustrative example:

w = waitforbuttonpress;
if w
       p = get(gcf, 'CurrentCharacter');
       disp(p) %displays the character that was pressed
       disp(double(p))  %displays the ascii value of the character that was pressed    
end

You can modify inputdlg so that the focus is automatically set on the enter button otherwise you have to push tab before enter.

MATLAB: How to keep asking the user for correct input even after they press enter

Most of the time case sensitivity shouldn't be a constraint in these types of queries. The demo below accepts any form of "ready" (READY, ready, Ready, reaDY, etc).

response = ''; 
while ~strcmpi(response,'ready')
    response = input('When you are ready to play please type "Ready": ','s');
end

If you truly only want to accept Ready and ready, use this condition instead,

while ~any(strcmp(response, {'Ready','ready'}))

Another form that gives the user feedback on their error,

 instructions = 'When you are ready to play please type "Ready": '; 
 baseInstructions = instructions; 
 response = ''; 
 while ~strcmpi(response,'ready')
    response = input(instructions,'s');
    instructions = sprintf('%s, (you typed "%s") ',baseInstructions, response);
end

Another idea since this is a binary task (the user types the correct word or they do not), why not use a question or message box?

qdh = questdlg('When you are ready to play, please press go!', 'Game', 'Go!','Go!');

You could also add a "Cancel" option.
