please help me .I have a database of 8 different fingerprint image to matching similarity from a input image and here the output . Anyone please guide me why the output is so long rather than 8 image matching.

Extracting features from D:\Simple_FingerPrint_Matching\indrani.tif ...
 >>> enhancement done.

what is the statement of line 31 in 'main_single' that is creating all the warnings? There's a call to the function sprintf that isn't shown.

[indrani dalui]

sir ,i am attaching a code here with

clear all; clc; addpath(genpath(pwd));
%% EXTRACT FEATURES FROM AN ARBITRARY FINGERPRINT
filename='E:\Simple_FingerPrint_Matching\FVC2002\DB1_B\101_1.tif';
img = imread(filename);
if ndims(img) == 3; img = rgb2gray(img); end  % Color Images
disp(['Extracting features from ' filename ' ...']);
ffnew=ext_finger(img,1);

%% GET FEATURES OF AN ARBITRARY FINGERPRINT FROM THE TEMPLATE AND MATCH IT WITH FIRST ONE
load('db.mat'); i=2;
second=['10' num2str(fix((i-1)/8)+1) '_' num2str(mod(i-1,8)+1)];
disp(['Computing similarity between ' filename ' and ' second ' from FVC2002']);
S=match(ffnew,ff{i},1);

clear all; clc; addpath(genpath(pwd));
%% BUILD FINGERPRINT TEMPLATE DATABASE
% build_db(9,8);        %THIS WILL TAKE ABOUT 30 MINUTES
load('db.mat');

%% EXTRACT FEATURES FROM AN ARBITRARY FINGERPRINT
filename='E:\Simple_FingerPrint_Matching\FVC2002\DB1_B\101_1.tif';
img = imread(filename);
if ndims(img) == 3; img = rgb2gray(img); end  % Color Images
disp(['Extracting features from ' filename ' ...']);
ffnew=ext_finger(img,1);

%% FOR EACH FINGERPRINT TEMPLATE, CALCULATE MATCHING SCORE IN COMPARISION WITH FIRST ONE
S=zeros(72,1);
for i=1:72
    second=['10' num2str(fix((i-1)/8)+1) '_' num2str(mod(i-1,8)+1)];
    fprintf(['Computing similarity between ' filename ' and ' second ' from FVC2002 : ']);
    S(i)=match(ffnew,ff{i});
    fprintf([num2str(S(i)) '\n']);
    drawnow
end

Change line 31 to

fprintf('%s', ['Computing similarity between ' filename ' and ' second ' from FVC2002 : ']);
