How do I add expectation operator of a variable in an economic model?

How do I write expectation operation in (suppose) the following equation on Matlab Editor?

where E is the expectation operator.

The expectation operator is generally considered to be the arithmetic mean. I don’t know what ‘x’ is (it could be a cell array, likely one vector in a cell array), but if it is a numeric array, the mean of one value is the value itself.
