Convert MATLAB code to mathematical notation

Hi!

I have a matlab code that I would like to write as a mathematical function. Unfortunately I'm not good with mathematical notations, and I'm not really sure where to begin - so any help would be much appreciated.

I have an array (for example):

x = [-1, 3, 2, 5, 6, 7, 9, 8, 6, 4, 1, -2, 0, 1];

I executed the following code on this array:

[~,latency_index] = min(abs(cumsum(x)-sum(x)/2));

The output I'm interested in is the latency_index. How can I write this code with mathematical notations?

Thank you very much in advance!

Most commonly the second output of min() of a vector would be referred to as "argmin"
