Which error do you get?

Whenever you post in the forum, that you get an error, add the complete message also. Currently an answer requires to guess what's going on, and if our guesses are wrong, an answer can be worse than no answer.

You may want to use uiwait() so the message pauses there and waits for the user, and does not keep barreling along with the rest of your code, as just a plain msgbox will.

message = sprintf('Disease identified as %s', DiseaseIdentified{1});
uiwait(warndlg(message)); % Waits, and displays exclamation point.

or, if it is normal

uiwait(helpdlg(message)); % Waits, and displays info text balloon.
uiwait(msgbox(message)); % Waits, and displays no icon at all.

Maybe is that what you want

msgbox(sprintf('Disease identified as %d',1));


msgbox(sprintf('Disease identified as %s',DiseaseIdentified));


i too did the second way but error as below....

??? Error using ==> sprintf

Function is not defined for 'cell' inputs.

Error in ==> PlantDisease>Neural_Network_pushbutton_Callback at 358

    msgbox(sprintf('Plant Disease identified as %s',DiseaseIdentified));

As it said, you can't use cell input in sprintf. You need to make sure DiseaseIdentified is a string.


msgbox(sprintf('Disease identified as %s',DiseaseIdentified{1}));
