Calling properties on an array of objects

Hello everyone,

I have an array with objects of a class I created myself: The array is called Users and the elements in this array are from type User, a class I wrote myself. I now want to update a property for every object in the array. Currently, I am solving this issue by using a for loop. However, I've tried to replace the loop with a vector operation like this:

Users(:).propertyName = operation(....)

I received the following error message:

Expected one output from a curly brace or dot indexing
expression, but there were 100 results.

Is there a way I could still solve my issue? Or will I have to stick with the for loop, which is pretty time-consuming?

Thanks in advance

[Users(:).propertyName] = operation(....)

If the operation does not have the same number of outputs as the number of entries in the array, then you might need

 [Users(:).propertyName] = deal(operation(....))

Now if the operation is a a non-static method of the object, how does it work? So:

[Users(:).propertyName] = Users(:).methodFromUserClass(...);

where the method I call is a non-static method from class User that I want to call for each object of the array Users. When I do it like this,

[Users(:).propertyName] = [Users(:)].methodFromUserClass(...);

I can't apply it because it says that the dot behind ] is invalid Matlab syntax.

Thanks in advance!
