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');

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
