Notes: calculates 2-norm distance from target vector to all query vectors syntax: dist = calcEuclidDist( target, query) Inputs: target: (d by 1) vector of the target vector query: (d by N) matrix of the query vectors (dimensionality is d, num samples is N ) Outputs: dist: vector of all 2-Norm distances

- calcAOIFixDensityDist calculate fixation density at the AOIs
- calcAOIFixDistHistDist Calculate fixation density for different distances from relevant AOIs
- calcAOIFixDurationDist calculate fixation density at the AOIs
- calcAOIFixSequenceDist calculate matrix representing the sequence of AOIs fixated
- calcAOISacDensityDist calculate target saccade density
- calcAOISacSequenceDist calculate matrix representing the sequence of AOIs saccaded to
- calcDistTraveled calculate the total distance traveled by the eye
- calcLatencyRelAOIFixDist get latency until relevant AOI fixated
- calcLatencyRelAOISacDist get latency until relevant AOI is saccade target
- codeFixationsDist identify fixations
