What have you tried? This seems fairly easy to do. Did you look for functions like diag?

[Ahmad Walid]

yes but it doesnt work, what is your idea for creating it?

As usual for homework questions: Please post what you have tried so far and ask a specific question. The forum will not solve your homework.

By the way, this is not twitter: no # before the tags. There is no need for a "matlab" tag, because this is a Matlab forum. Thanks.

Use the functions triu, diag and tril .

Another option is to start with zeros(m, n) and running 2 for loops. Then compare the indices:

if i1 == i2
    A(i1, i2) = exp(i1)
elseif i1 < i2
    ...
else
    ...
end
