MATLAB: Inputdlg if ok pressed load this code

Question

Hi all,

i am developping an app in APP designer and this is a part of my code.

i am looking for a way to : when the user clicks on "OK", the user inputs get stored to a file, else if the user selects cancel then it cancels.

QUESTION : How to use "if " to tell matlab that the user clicked on OK !

thanks

prompt = {'Cell Voltage (V)','Cell Capacity (Ah)'};
            dlgtitle = 'Add New Battery';
            dims = [1 100; 1 100];
            definput = {'Cell Nominal Voltage','Nominal Capacity'};
            answer = inputdlg(prompt,dlgtitle,dims,definput,'on');
            
            if ( user clicks on "OK" then this code is used)
            V_Cell_Nom = str2double(answer{1});
            C_elb = str2double(answer{2});
            
            
            fileID = fopen('exp.m','a+');
            fprintf(fileID,'%s %d \n','V_Cell_Nom = ',V_Cell_Nom);
            fprintf(fileID,'%s %d \n','C_elb = ',C_elb);
            fclose(fileID);
            
            elseif ( user clicks on "cancel", then stop the program)
                return;
            end

if isempty(answer) % user clicked 'Cancel' or closed the dialog box without clicking 'OK'
    return
end
% user clicked 'OK'
% do stuff
