MATLAB: Vector loop over multiple object handles inside a set function

Question

Hi,

following problem: I have an array of struct elements with each containing a handle element (surface object in my case) for which I want to set the Visible property to an equivalent cell array containing 'on' and 'off'.

Here is how I would imagine the code line to look similar with:

set([structWithStuff(:).surfaceHandle], 'Visible', cellArrayWithOnsAndOffs(:));

The code above obviously is faulty. Assuming, this is even possible within MATLAB, what would be an appropriate way to make this work? Or would the more efficient way actually be a simple for loop?

Answer 1

No for loop is required. See the "Set Line Style to Different Value for Multiple Lines" and "Set Different Values for Multiple Properties on Multiple Objects" examples on the documentation page for the set function. The first input should be a vector of handles, the second the cell array {'Visible'}, and the third the cell array of values to which the Visible property of the objects in the vector of handles should be set.

In the first of the examples on the documentation page P is a vector of 4 handles, NameArray is a 1 element cell array, and ValueArray is a 4 element cell array.

In the second documentation example S is 3 handles, NameArray has 2 elements, and ValueArray is 3-by-2.
