The following link might help in creating a 3 variable Karnaugh map in MATLAB.

https://www.mathworks.com/matlabcentral/fileexchange/6853-kmap

To create a 3 variable Karnaugh map, the function mymap available in the above link can be modified as shown below.

if nargin == 0
    map = zeros(2,4);    
    for i = 0:1
        for j = 0:3           
            map(i+1,j+1) = str2num(mybin2dec([mydec2gray(num2str(i)) mydec2gray(num2str(j))]));
        end
    end
end

when i make these adjustments to the function mymap, I am getting an error of not enough input arguments in the solveKmap function. How do I go about fixing this?

[Walter Roberson]

How are you invoking the function? Are you using the gui provided?

Hi Mohit

The solveKmap function available in the file exchange is written for 4 variable Karnaugh map. You need to modify the code in the solveKmap function suitable to provide outputs for a 3 variable Karnaugh map.

Also, the error of not enough input arguments in the solveKmap function is due to the non provision of input while calling the function. The input to the solve Kmap function can be a 2 X 4 matrix as shown below.

kmap = [0 0 0 1; 0 0 1 1];
