Hello,
I am having a bit of trouble trying to extract elements out of
nested lists. I have an X x Y array where each element of the array is
a 3x3 matrix. I am trying to make density plots of each component. For
example, I would like to plot the 1,1 components of each element of the
larger array. I have tried the following:
Array[g[[i,j][[a,b]],{i,Dimensions[g][[1]]},{j,Dimensions[g][[2]]}]
where I am trying to get the a,b component
This does not work, and I am not seeing exactly why not. I am hoping
someone can point out my error or suggest a way to extract the lists I
need.
Thank you,
