Syntax for multiple summation that uses a data file!

Syntax for multiple summation that uses a data file!

(OP)
Hello,

I have a binary file containing a 3 dimensional array (time, vertical, horizontal).
I would like to perform some noise statistics on it but Im not very proficient at Maple.


The equation that I would like to run it through has a total of 6 summations. 3 of these summations use the time
(t), vertical (v) and horizontal (h) as the index and are
performed inside 3 other summations (indexes,  t', v', h').

Looks something like:
 E E E (E E E   U(t,v,h)  * f(n) )^2    
where U(t,v,h) is my 3d array, and f(n) is an exponential function dependent upon t,v,h,t',v', and h'

I uploaded the equations here:

If anyone could point me in the direction on how I would enter this
in Matlab I would be eternally grateful!

Thanks,
Eric
