What is looked for here? Whats the output that is expected from the sample vector? Can you show the code that you tried and where you struck?

I think that your problem is the function definition. Actually you are using total as input and v as output and I think that your intention is the opposite. The function should be:
function [total]=grade_eyad(v)
min(v);
mean(v);
v(min(v))=mean(v);
total=sum(v)
end
When you have these code saved, you can use:
v=[12 9 6 10 13];
total=grade_eyad(v)

function total = grade_eyad(v)
[~,idx] = min(v); %finding the position of the minimum value (3 in the given example)
v(idx) = mean(v); %replacing the value (Christians code will replace the 6th element (13)
total = sum(v);
end
or you could index in another way (will be better if there are more 6'es to be replaced)
function total = grade_eyad(v)
v(v == min(v)) = mean(v); % find all instances where v equals min(v) by the == operator and replace by mean(v)
total = sum(v);
end

save the function as grade_eyad.m
Then you'll be able to call it from your workspace with an output with any name you like and with alterations to v (or use another variable name if desired).
v = [12 9 6 10 13];
total = grade_eyad(v)
w = [12 8 5 8 8 6 8 10 13 10 11];
total_w = grade_eyad(v)
