Hello all,
I have a multidimensional array of 300x430x180. I need to efficiently calculate and store:
  • An average value per frame
  • The st.dev
  • The median per frame
  • The range per frame (the difference between the lowest/highest value in each frame)
Essentially my ideal output is a structure that contains
  • AvgValues (1x180)
  • St.dev (1x180)
  • Median (1x180)
  • Range(1x180)
I wanted to implement this into a for loop so it can run and store these values as it goes through the 180 frames. I am definitely overthinking this and need someone to point me in the correct direction.

You can reshape the matrix into 2D and use the respective functions.
A = rand(2,2,5) ;
A = reshape(A,[],5) ;
Avg = mean(A) ;
