I have a cell array size 99x2 (xStates). The first column are matrices with x,y pairs on the first and second columns respectively. The second cell array column has ID's for each of these coordinate pairs.
For each iteration I have a pair of x and y (xloc and yloc) to compare to the coordinates in the cell array, and if found, extract the corresponding ID and indices to a new matrix.
curScan is an indexing variable for the main loop that goes up to 99.
Here's what I got so far:
detectedAsTrack = 0;
detectedTracksList = [];
if find(xStates{curScan,1}(1,:)==xloc, 1) > 0 && find(xStates{curScan,1}(2,:)==yloc,1) > 0
detectedAsTrack = 1;
detectedTracksList(curScan) = xStates{curScan,2} (insert index for ID that corresponds to xloc and yloc);
end

xStates{curScan,1}(1,:) only inspects the first row of each matrix. Is that what you're trying to do, or do you want the column of x coordinates? (Same for the second comparison inspects the second row)

@Chris So I actually want to check row 1 of every column for x, and row 2 of every column for y. This is what each cell on xStates{:,1} looks like:

detectedAsTrack = 0;
detectedTracksList = [];
idxs = xStates{curScan,1}(1,:)==xloc > 0 & xStates{curScan,1}(2,:)==yloc;
if any(idxs)
detectedAsTrack = 1;
detectedTracksList(curScan) = xStates{curScan,2}(idxs);
end
