eg: imageCells - cell array contains 8 images (double array)

```t = {'descend','ascend'}
imageCells  = arrayfun(@(i1)sort(rand(200,200,3),randi(3),t{randi(2)}),1:8,'un',0)
```
```A=[115.9607 118.7609 118.7595 118.7681 118.3420 118.1658 118.0285 118.0862];
query=118.7595;
t = abs(A - query) < 100*eps;
if any(t), imshow(imageCells{t}); end
```
