How to save .mat file in a function?

Hello, i have a function, i wanna save the result to .mat file. i try to execute save example.mat result , but i doesn't work. what should i do? this is my function

function result=plus(images)
[rmax, cmax] = size(images);
  for row = 1:rmax;
    for col = 1:cmax;
    
    if images(row,col)== 1 
    a=14;
    b=2;
    result=a+b
    end
    end
  end
  save example.mat result

I purposely don't add a semicolon in the "result = a + b", in order to show the row and column which produces number 16

thanks in advance

Your last line should be

save('example.mat', 'result');

Thank you for your reply, but i think it's still the same with my code. i mean that, when you run the code above, it results 16,16,16,16...so on. But, why the example.mat only have matrix 1x1, it's doesn't has the same matrix with the result which is 16,16,16...

It's unclear what you expect 'result' to be. You define 'result' to be a+b, which will always give you 16 since you have defined a=14 and b=2. In what sense does your code not work?

i'm not focus on the value of result. it's free to be what you want 16,12,3,5.., and so does the a&b value, it's free to be what you want 1,3,4.. i just wondering, why example.mat only has matrix 1x1, whereas the results has so many number

You are writing over all of the variable "result" on every iteration of the loop. Try

result(row, col) = a+b;

Thank you for your reply, but it takes all the row and col. How to display only the calculation of a+b and also the matrix contain only the calculation? for example the results are 16,16,16,16.. so, the matrix also only contain 16,16,16,16.. not all the row and col
