Operator '==' is not supported for operands of type 'table'.
Error in working_try_2 (line 98)
if(T(:,1)==string(label))
%%code
faceDetector=vision.CascadeObjectDetector;
while true
img_again=getsnapshot(video);
pause(2);
bbox=step(faceDetector,img_again);
if(sum(sum(bbox))~=0)
es=imcrop(img_again,bbox(1,:));
es=imresize(es,[227 227]);
label=classify(myNet1,es);
image(es);title(char(label));
% comparion of the found image with the student database
if(T(:,1)==string(label))
disp(strcat('Student=',string(label)));
disp('Found');

%use Compare strings
strcmp(T(:,1),string(label))
%or Compare strings (case insensitive)
strcmpi(T(:,1),string(label))
Check this: strcmpi or strcmp

% comparion of the found image with the student database
if(strcmpi(T(:,1),string(label)))
disp(strcat('Student=',string(label)));
disp('Found');
col={'ID','Attendance'};
dat={string(label),'P'};
unitable('columnname',col,'Data',dat);
end
it doesnt disp the statements under the if condition and directly goes to the next condition
