I suggest you make a 5x3 matrix, for example,
FingerAngle=rand(5,3);
Then call the function for the first finger
kin(FingerAngle(1,1),FingerAngle(1,2),FingerAngle(1,3))
For the second finger, it will be
kin(FingerAngle(2,1),FingerAngle(2,2),FingerAngle(2,3))
Or a little bit advanced, use cell array
FingerAngle=num2cell(rand(5,3));
% for the first finger
kin(FingerAngle{1,:})
% for the second finger
kin(FingerAngle{2,:})
