Sir, how to calculate Euclidean distance of two cell array having the size testdata 1 X 30 and traindata 1 X 50 of 10 person (8 images per person)

Sir, how to calculate Euclidean distance of two cell array having the size testdata 1 X 30 and traindata 1 X 50 of 10 person (8 images per person)

Answer 1

[KSSV]

Read about pdist and pdist2.

[Balaji M. Sontakke]

Sir, Just I have used the function pdist2(traindata,testdata); here, testdata{p}=ext_finger(img,1); traindata{p}=ext_finger(img,1); testdata and traindata are cellarrays Sir, I would like to know that, pdist2 is used for calculating Euclidean distance from cell array.

[Balaji M. Sontakke]

I got following error

>> pdist2(testdata,traindata) Error using pdist2 (line 142) X and Y must have the same number of columns.

here, testdata having size 1 X 3 cell, traindata having size 1 X 8
