How to get all values existing in arrays/matrices?
Ältere Kommentare anzeigen
Hello,
Let say I have a 3-by-2 array with random integer values. For example,
myArray = [98 56; 58 52; 100 56];
What I want to do is, I want to get all value in the array and its frequency and save it to another array like this,
listValue = [98 1; 56 2; 58 1; 52 1; 100 1];
Is there any function or a way to do it?
Thank you in advance.

Read about unique
a = myArray(:) ;
[cnt_unique, unique_a] = hist(a,unique(a)) ;

See unique() and accumarray. Or unique and histc or histcounts (but be careful about the last value in histcounts). Or use a loop. Or use sparse(). Lots of ways.
