This link shows how to sort an struct array by a certain field: https://stackoverflow.com/questions/25047590/sorting-array-of-objects-by-property-in-matlab

Using this method every time I need to insert a new element I have to insert the element in a arbitrary position and sort it again.

I want to insert the element directly in the correct position. Matlab already have a way to achieve this? Or I need to implement it?

if you're worried about having the implement the insert+sort every time, you can package that into a method of the class (and even overload "sort"). Stijn's link will help if you already know which index you want to insert into, but if you don't know then you can't avoid the sort either before or after - in which case might as well be after.
