How to document the input from Matlab into the file

Hi all,

I have a code that allow user to enter multiple inputs via 'For' loop. However, I usually don't remember the inputs unless I have to note them down before running the MATLAB. Hence, I am wonder if there is a way to output or save all the inputs that I entered into a file right after MATLAB run. Below is the example of my inputs with for loop. Thank you guys. Much appreciate.

count=input('Enter numbers of item:');
for k=1:count
    %%%Below here are the inputs for every loop, count 
        fprintf('Please enter BMP number %0.0f information, start with the deepest one \n',k);
        shape=input('1 = rectangular,2 = circle,3 = ellipse,4 = polygon: ');
        nlayers=input('Enter number of layers for this BMP: ');
        ind=input('Set type of BMPs, 2=pervious pave, 3=bioretention, 4=grass swales: ');
            if shape==1 %Rectangular
                %%%code 1
            elseif shape==2 %Circle
                %%%code 2
            elseif shape==3 %Ellipse
                %%%code 3
            else disp('This is polygon (triangle, rhomnus, hexagon, etc)')
                %%%code 4
            end 
end

How about fprintf?

Using input in the command window is useful for short hacks only. For real applications either use a GUI and store the inputs by writing files (see: doc fprintf). Or create the files in an editor and import them (see: readmatrix, fscanf, etc).

Alternatively create a script or function, which defines the inputs and call the function directly. Using Matlab's editor is more comfortable than the command window, because the results are reproducible. A typo inside the input using input() will be very confusing and hard to find.

Thanks alot Jan, it works
