I have four a cell with four arrays each containing around 5000 numbers (all arrays have the same length). I call these arrays
On the other hand, I have the prescribed values for these four parameters
and I need to find the combination of s,k,I,G that is closest to the values of s0,k0,I0,G0. It is important to note that s,k,I,G have to be in the same row (i.e., not s(10), k(1), I(1001), G (50000), but, for instance s(888), k(888), I(888), G(888) are the closest to s0,k0,I0,G0).
Please can you give me some hits how to tackle this problem? Would this be a minimize the function problem?
Thank you,

Seems like a simple application of min()
[minval,rownum]=min(sum( abs( [s-s0, k-k0, I-I0, G-G0] ) , 2 ) );
