The scalar result is caused by the use of matrix division rather than element-by-element division. Replace '/' by './'. Similarly replace '^2' by '.^2' .

thank you but can you help me with this problem too?

It looks as if the dot in front of the asterisk in ".^2.*1.79" is being mistaken for a decimal point after the 2. Try putting parentheses around the 2: ".^(2).*1.79"

You put x as numerical Data.

If you want to get result in terms of x then x has to be defined as a symbolic variable. i.e.,

syms x

This would give you the desired result.
