Hi! I have been working on a document where I am translating lines of IDL code into Matlab. There are a few lines that I have been stuck on and I would super appreicate some help with. They are as follows in IDL:
rad = double(swap_endian(( assoc(1,intarr(5760,2880)) )[0])) + 3396000.d0
dci = ( assoc(1,fltarr(5760,2880)) )[0]
Both lines deal with the assoc function which I cannot find a good substitute for in Matlab. Thanks so much!

Hi Joseph,
Please refer to the MATLAB converted code below:
%First line
array = zeros(5760, 2880, 'int32');
%Convert the first element to double, swap its bytes and then add 3396000.0
value = double(swapbytes(array(1))) + 3396000.0;
%Second line
array = zeros(5760, 2880);
%Access the first element
dci = array(1);
Please refer to the below mentioned documentations for more information on:
  1. swapbytes - https://www.mathworks.com/help/matlab/ref/swapbytes.html
  2. zeros - https://www.mathworks.com/help/matlab/ref/zeros.html
