hi
I need to know that if there is way to call all properties in the class without calling their name. I write many function for all properties by one by. So I need one function and that contains all properties.
for example I use this:
classdef class
properties
x
y
z
end % properties
methods
function obj = d(obj,x)
obj.x(1).value(1)=x(1).value(1);
obj.x(2).value(2)=x(2).value(2);
end%functions
function obj = e(obj,y)
obj.y(1).time(1)=y(1).time(1);
obj.y(2).time(2)=y(2).time(2);
end%functions
function obj = e(obj,z)
obj.z(1).something(1)=z(1).something(1);
obj.z(2).something(2)=z(2).something(2);
end%functions
end%methods
end %class
but I want to use something like that:
classdef class
properties
x
y
z
end % properties
methods
function obj = xxxx(obj,allproperties)
obj.prop.1(1).value(1)=x(1).value(1);
obj.prop.1(2).value(2)=x(2).value(2);
obj.prop.2(1).time(1)=y(1).time(1);
obj.prop.2(2).time(2)=y(2).time(2);
obj.prop.3(1).something(1)=z(1).something(1);
obj.prop.3(2).something(2)=z(2).something(2);
end%functions
end%methods
end %class
is there any way to provide all properties without calling them seperatly.
thank you for now.

The organization of your properties and data looks strangely complicated.
Regardless, though, you can use dynamic field names to access properties
propnames={'x','y','z'};
for i=1:length(propnames)
obj.(propnames{i}) = whatever
end

See documentation on:
  • meta.class class describes MATLAB classes and
  • meta.class.fromName. Return meta.class object associated with named class
