I am trying to get the indices and values from a vector based on a condition. I used find for that but the values it returning are logical values. How can I get actual values? An example is:

X = [4; 5; 1; 0; -7; 3; 0; 1; -4];
[row, ~, val] = find(X>0 & X<6)
row = 5×1
     1
     2
     3
     6
     8
val = 5×1 logical array
   1
   1
   1
   1
   1

I want val to have 4 5 1 3 1
