[A_uni,ind1,ind2,Ac]=cunique(A);
Description
The imx function provides a figure window based GUI for 3D image segmentation
Examples
Plot settings

Example 1: Getting unique entries and occurance counts for 1xN arrays
n=15; A=round(25*rand(1,n)); %Rounded random set in range 0-25 A(1)=A(end); %Force at least one double occurance for this example A %Get unique set and counts [A_uni,ind1,ind2,Ac]=cunique(A)

Visualizing input array and occurange counts

Example 2: Getting unique entries and occurance counts for NxMx... arrays
