Hi, guys, I am attacking one proble and may need your help. I have a large matrix(m*n). I wanna to sort out the matrix from large to small according to its element's value AND save the corresponding row and column number as its position. Latter on, plot out the first 20 largest value accroding to their positions. Is there any good way to do this, especially take out the positons of element and assocate it with the value?
