Trying to request user input and then perform if elseif else end function...

I have a for loop which generates a figure on each loop. Based on what I see in the figure, I want my code to request a user input of either Y or N.

Then, on input of either Y or N, I would like to add a row to an output matrix, which I will ultimately write to a .csv.

The first column in each row will be the filename of the figure, and the second column, either 'yesboat' or 'notboat' depending on whether the input is Y or N.

This code isn't working AT ALL but it's what I have pulled together from the help files... if you have any suggestions to make it work, I would be very grateful.

Also, which is the best way to create an empty output for storing text info. such as this? My filenames are numbers at the moment but I would like them to be stored as text.

 %create output array, table with two columns
        output=[];
        row=1;
        
        prompt='Can you see boat noise? Y/N';
        x=input(prompt);
        
        if x=='Y'
            %store filename in output with 'boat' in second column
            output(row,1) = filename; %e.g.5103.190828112504 /variable.yymmssHHMMSS 
            output(row,2) = 'yesboat';
            
        elseif x==N
               %store filename in output with 'no boat' in second column
                output(row,1) = filename;
                output(row,2) = 'noboat';
                
        else
            disp('Input must be Y or N!')
            
        end
           
        row=row+1;

"...which is the best way to create an empty output for storing text info..."

Use a cell array or a string array, e.g.:

out = cell(N,2);
for row = 1:N
    prompt='Can you see boat noise? Y/N';
    x = input(prompt,'s'); % need 's'
    switch upper(x)
        case 'Y'
            out{row,1} = filename;
            out{row,2} = 'yesboat';
        case 'N'
            out{row,1} = filename;
            out{row,2} = 'noboat';
        otherwise
            ...
    end

Thanks! I realised just after I posted that I am missing the 's'... and I did this...

str=string();
row=1;
 
 for i=1:5
        
        answer=input('Can you see boat noise? y/n: \n', 's')
        
        if strcmp(answer,'y');
            %store filename in output with 'boat' in second column
            str(row,1) = 'filename';
            str(row,2) = 'yesboat';
            
        elseif strcmp(answer,'n');
               %store filename in output with 'no boat' in second column
                str(row,1) = 'filename';
                str(row,2) = 'noboat';
                
        else
            disp('Input must be Y or N!')
            
        end
           
        row=row+1;
 end     
 
 

...however for some reason the code works but I get this printed in my command window each time... any ideas why this '8___ ' appears??

"...any ideas why this '8___ ' appears?"

It looks like MATLAB might be in some debugging mode. Do you have any breakpoints set?
