I have to solve for sigma c in the attached pdf and need some help converting it from Mathcad to Matlab. Can someone help me translate the code to Matlab? Here's the sizes of m,n,j:
%m = 1:71;
%n = 1:41;
%j = 1:512;
Thanks!

And your attempt is where and you got stuck on what part, precisely???

What is the pseudo-code for the a conditional term?; I can't decipher the Matchcad-ese, sorry. Specifically, if I presume it's something like
a=dp/6;
a(0)=2*p(0)+p(1);
a(N-1)=2*p*(N-1)+p(N-2)*p(n-1)+4*p(n)+p(n+1);
then since the if implies n==N, then p(n+1) would seem to have a bounds problem???
And, of course, what are p, delta-p, k, etc., etc., ...

for m ε 0..M - 1
translates to the MATLAB code
for m = 0 : M - 1
However, keep in mind that in MATLAB, subscripts start at 1 instead of 0, so anywhere you wanted to use m as a subscript you would need to add 1 to it. Mostly you would end up writing as
for m = 1 : M

"... work ahead of this snippet that's not functioning correctly."
And we were to be able to divine that how, precisely???
