Not able to get count of each elements in array itself

3 views (last 30 days)
I am having this array..x=[ 1 2 3 1 2]
Now I want to replace it with count of the corresponding elements..here x should get modified to x=[2 2 1 2 2]
By using hist(x, unique(x)) I am able to do it but it gives the count for unique elements. I want the result to have the number of elements.
please help!

Hi Scott,
Instead of using the histc function, you can use the grouptransform function to get the count of all elements int the array.
x = [1 2 3 1 2];
x = [1 2 3 1 2]';
x = grouptransform(x,x,@numel);
x contains the required array.
