Calculates color difference delta E of a set of sRGB data pairs

sRGB2CIEDeltaE Calculates color difference deltaE of a set of sRGB data pairs

function deltaE = sRGB2CIEDeltaE(SamplesRGB1,SamplesRGB2,formula)
Calculates color difference, deltaE, of a set of sRGB data pairs, SamplesRGB1 and
SamplesRGB2(both within[0 1]).
CIEDE1994, CIEDE2000 and CIELAB are alternative according to user input
formula, which can be 'cie94', 'cie00' and 'cielab'(case sensitive).
SamplesRGB1 and SamplesRGB2 should have the same size, N*3, with each row
denoting a sRGB triplet and N for the number of sRGB pairs to be
compared. Generally, but not always, SamplesRGB1 is regarded as standard
references
Example1:
>> sRGB2CIEDeltaE([0.42 0.77 0.37],[0.50 0.83 0.46],'cie00')
ans =
4.4351
Example2:
>> sRGBpairs1 = [0.1743,0.0819,0.0541;...
0.5565,0.3047,0.2208;...
0.1091,0.1999,0.3428];
>> sRGBpairs2 = [0.1225,0.1388,0.1083;...
0.3423,0.3626,0.2826;...
0.1365,0.2390,0.3095];
>> sRGB2CIEDeltaE(sRGBpairs1,sRGBpairs2,'cie94')
ans =
11.5193
19.4527
32.0004
