Write a computer code (in Fortran or another language) to check the identity

εijkεpqk = δipδjq - δiqδjp

where i, j, k, p, q are subscripts (with values from 1, 2, and 3, hence 81 total possible values, and k is the free variable)

for all 81 possible values of i,j,p,q. The program should include
function subroutines for computing epsilon(i,j,k) and delta(i,j).
Using the epsilon function subroutine, also compute εijkεijk.

Lab report should include a description of the purpose of the code,
the code itself including comment statements, a short user
guide, plus output and an explanation of the output. Grading will
include a component for elegance and efficiency of the code and
output.

If anyone can help me, that would be very awesome.

Anybody please?

BUMP

only 5-8 regulars frequent this subforum of which i only know like 4 that actually know how to program. if no one answers its basically because we are lazy or dont feel like helping. and the bumping doesnt really make us help anyone more after all posts dont get off of the first page until weeks after posting.

maybe i'm missing something but for the basic logic why can't you just do this with 4 nested loops. I know its sloppy, but should work. Something like this (python):

I appreciate the reply. Can someone help? Please?

where do you get the functions epsilon and delta from?
maybe you have a standard definition in your curriculum

otherwise it looks pretty simple to do in fortran v

@azrad - you misread it seems, loop-counter would have to be (1,3) and not (1,4)

i haven't bothered because 1) i dont know fortran and 2) if he's allowed to pick any language he wants, i dont know why he would pick fortran if he doesn't know it either

cs hipster

i totally understand why you said that, but in python that is not how it works...
here is a snippet with its output:
