For a three dimentional matrix: A=randi(10,[10 10 5]), I want to find the index (x,y,z) of each non-zero element of A and then rank the all the non-zero elements according to the value.
However, when running the following code, it seems 'find' can only have three outputs. May I know how to achive this?
A=randi(10,[10 10 5]);
[x,y,z,val]=find(A);
sortrows([val,x,y,z],1)

You can use my FEX submission findND.
A=randi(10,[10 10 5]);
[x,y,z,val]=findND(A);
sortrows([val,x,y,z],1)
