Easiest way for you is probably to just add the numbers and divide (i.e. calculate the mean manually).

Thank you for your reply EViews Gareth but I have ever try
the way as your recommend.
by @sum(.......)/7
zresult_{%n}(10,2) = @sum(@mae({%n}_r{!m}f,{%n}))/7
but the program tell the error that
Scalar sent to function which operates on a matrix in
"ZRESULT_{%N}(10,2) = @SUM(@MAE(BMIX_E_R1F,BMIX_E))/7".
Because i don't understand truly about type of object and how to manage them.
How can I solve the problem.

Just use + rather than a function.
