how can i solve the error: operator -: nonconformant arguments

enter image description here

this is the problem that is about digital signal professor does not want let me use for function so i tried using sum function this is what i tried:

>> n = -10:10;k = -5:5;x = sum(exp(-abs(k)) .* ((n-2*k)==0));

[error: operator -: nonconformant arguments][3] (op1 is 1x21, op2 is 1x11)

i know why it makes error but i don't know how to sum with two variables...

I found the solution:

>>  n = -10:10;>>  k = -5:5;>>  x = exp((-abs(k))) * ((n-2*k')==0);>> stem(n,x,'filled');
