Perhaps the title of my question isn't phrased at best, but hopefully the description will provide clear insight. I have the following couple of arrays:
idListReq = {'stock.A', 'stock.A', 'stock.A', 'stock.B', 'stock.B', 'stock.B', 'stock.B'};
factorData = [1, 4, 2, 9, 10, 1, 3];
Each element of idListReq has its numerical assignment in factorData. I would like to get the maximum across the groups of values that are tied to a single ID (e.g. values for 'stock.A' are 1, 4 and 2, meaning the max will be 4).
The desired outcome should like this:
idList = {'stock.A', 'stock.B'};
What I used at the beginning was cellfun, and it worked, but I want to know if there's a better way for this, without using loops.
fData = cellfun(@(x) max(factorData(strcmp(idListReq, x))), idList);
Best regards and thanks in advance!
