I have a large matrix of size 50000×3. I would like to replace the values of the elements with a new values. To illustrate my problem, for example, let's say F is as follows.
F = [22 60 100; 11 13 14; 10 12 15; 16 15 17; 17 18 25; 13 19 20; 20 30 22; 10 11 12] unique(F)' = 10 11 12 13 14 15 16 17 18 19 20 22 25 30 60 100
Now I want to assign new values to each element of F. The assignment is such that the lowest value of F maps to 1, the second lowest value maps to 2. It continues with an increment of 1 until it reaches the highest value in F. In the example above, I want to assign 1 to 10, 2 to 11, …, and 16 to 100 and construct a new F as follows:
Fnew = [12 15 16; 2 4 5; 1 3 6; 7 6 8; 8 9 13; 13 10 11; 11 14 12; 1 2 3] unique(Fnew)' = 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
Could someone instruct me how to construct such a matrix from F?
