Hey all, quick question:
Say I have some data:
a,b,c
2,3,4
5,6,7
8,9,10
And an equation:
0=((a-b)./c)-R
and I want to solve for R for each of the rows of data, how would I create an iteration for that? I can call the data from a .csv file, and output the results as well, but I've never set up an iteration myself. As a side note, the data may have x variables (columns) and I may need to iterate n number of times.
Thanks.

I'm not sure if that's really what you want to have:
Define a matrix
A=[2,3,4;5,6,7;8,9,10];
R=((A(:,1)-A(:,2))./A(:,3));
Results for your axample are:
R =
-0.2500
-0.1429
-0.1000
If you want to use a csv file, please have a look at the command csvread.
I hope this answers your question.
