why it does not work ?

function out = block3(row, colomn)
a = zeros(row, colomn);
for i = 1:row
    for j = 1:colomn
        if ~mod(i,2) && ~mod(j,2)
            a(i, j) = 1;
        end
    end

You ask why it does not work. In order to answer that question, we need to know what it should do, but you haven't told us that. What should this function do?

• missing end statement
• no assignment to the output variable out

ok that is right thank you. but even if i do not assign the out put does it can be problom to me becaues until it is empty it does not matter. right.

[EZRA]

function block3(row, colomn)

a = zeros(row, colomn);

for i = 1:row

for j = 1:colomn

if ~mod(i,2) && ~mod(j,2)

a(i, j) = 1;

end

end

end

Wild guess: Perhaps the function should output the variable 'a'.
