MATLAB: Put the coordinates from a string to a array

Question

I have to put the coordinates that come from a string in an array

value = 2498536 1117123 412 2498543 1117124 412 2498543 1117124 414 2498536 1117123 414 2498536 1117123 412

I need to extract the value and put them as number in a array. I would like to put them three by three like this

2498536 1117123 412 
2498543 1117124 412
2498543 1117124 414
2498536 1117123 414
2498536 1117123 412

What would be the easier way to do this ?

Thanks for helping

Answer 1

val = '2498536 1117123 412 2498543 1117124 412 2498543 1117124 414 2498536 1117123 414 2498536 1117123 412' ;
iwant = reshape(str2num(val),3,[])';
