MATLAB: How to change multiple fields in a nested structure

Question

I am trying to change the color of plots in a graph through the figure handle. The figure handle is part of a structure of figure handles. Each plot has a marker and a line and the Color property of each marker and line is nested in the structure as follows

plot 1 line color for Figure n: h(n).Children.Children(1).Color

plot 1 marker color for Figure n: h(n).Children.Children(2).Color

plot 2 line color for Figure n: h(n).Children.Children(3).Color

plot 2 marker color for Figure n: h(n).Children.Children(4).Color

etc.

For a given Figure n, I would like to set the Color property for both the marker and line for a plot at once, e.g. I would like to change the color of plot 1 by assigning a single value to h(n).Children.Children(1:2).Color.

Here is my attempt with setfield

h = setfield(h,{12},'Children',{1},'Children',{1:2},'Color',[1 0 0])

But this gives me this error: Error using setfield (line 56) Insufficient number of outputs from function on right hand side of equal sign to satisfy overloaded assignment.

Answer 1

You should be able to do this via set:

set(h(n).Children.Children(1:2), 'Color', [1 0 0]);
