You need to convert your cells into matrix and then call _pdist2).
testdata = cell2mat(testdata) ;
traindata = cell2mat(traindata) ;
pdist2(testdata,traindata);

Sir, actually the block[50 X 6] contains 'minutiae' information which contains the following data in columns [X, Y, CN, Theta, Flag, 1]and rows contains number of minutiae information on the dorsalhandvein. if i go like this the matrix size increase, so I want to reduce minutiae information which is in row. sir is there any function to reduce row size.
