How can we get an array of ordered pairs from the user?

I wanna get an array of ordered pairs from user, but in this program we dont know the number of ordered pairs(it can be Changeable) ...Is there any way for this?

for example: I have a 512*512 zero image and I want to change this {(234,90),(120,23),(145,243),(255,75)} to one...the user enter this values...How can I get this values as an array

Jack - how are you asking the user to provide the ordered pairs? Through a GUI or through command line requests?

through command line requests.Is it possible?

It would be much easier to provide the data as a script, wuch that you can edit the data and call the function multiple times without the need to type in all data again:

values = [1,2; 4,5; 8,12; 241, 243];
YourFunction(values)

thanks Jan I have an a matrix: m=zeros(512)

I want to get some ordered pairs from user and if the user enter{(2,4),(66,90),...} the value of these element should be 1 in this matrix .after that I can do my function.
