i got index exceeds matrix dimensions.??

my vector_database table have 4 columns

%%Test Ear

clc;

clear all;

close all;

[fname, path]=uigetfile('.jpg','provide ear for testing');

fname=strcat(path,fname);

im=imread(fname);

imshow(im);

title('test ear');

%%find out which class it belongs

Ftest=FeatureStatistical(im);

%%Compare with Database

conn = database.ODBCConnection('test','root','');

curs = exec(conn,'select * from vector_database');

curs = fetch(curs);

curs.Data

Ftrain=curs(:,2:3); <-(Index exceeds matrix dimensions.)

Ctrain=curs(:,4);

for(i=1:size(Ftrain,1))

dist(1,:)=sum(abs(Ftrain(1,:)-Ftest));

end

m=find(dist==min(dist),1);

det_class=Ctrain(m);

msgbox(strcat('detected class=',num2str(det_class)));

You should put a breakpoint at that line and then check the dimensions of the curs variable. without running your code and without and example to bring in this is the best approach. I'm suspecting that you're not accessing "curs" the way you think and it is probably a struct. You're probably looking for curs.Data(:,2:3)
