Hi folks,
I'm looking to conduct a linear optimisation and was hoping for some help on the matter.
I have 56 columns of data, with 256 rows each; lets call this set A. I have another column of data, with 56 rows; lets call this set B. I essentially want to correlate each of the 256 values in each column of set A to a single value in set B; lets call this set C.
I want to know which of the 256 values across set C give the best correlation between sets A and B. In other words, which row in set A gives the best correlation to the corresponding value in set B, across all columns of set A.
Any help on this matter would be most appreciated!

Diffs=abs(reshape(B,1,1,[])-A);
d=min(Diffs,[],3);
[Arows,Acols]=find(d==min(d(:)));

Ran in:
A=load('inputVariables').sum_Coke;
B=load('inputVariables').CRI;
B=B.CRI;
whos A B
Name Size Bytes Class Attributes A 256x54 110592 double B 54x1 432 double
Diffs=abs(reshape(B,1,1,[])-A);
d=min(Diffs,[],3);
[Arows,Acols]=find(d==min(d(:)));
whos Arows Acols
Name Size Bytes Class Attributes Acols 84x1 672 double Arows 84x1 672 double
