I have a 3x3 matrix: J=[0 3 4;3 0 8;4 8 0]
and I want to know in which position the elements exist. For example that 8 exists in second row and third column (2,3) and (3,2) too.
After that I want a new matrix with the value (i.e. 8) in one column and their ''coordinates'' (i.e. 2,3) in a column side by side.
Thanks
