Compare classes with different Properties
显示 更早的评论
Hi
Is there an easy way compare classes of the same type with variable attributes ?
I have an array which contains instances of a class
example would be something like this
instance 1
classdef MyClass
properties
a = 1;
end
methods
end
end
Instance 2
classdef MyClass
properties
a = 2;
end
methods
end
end
So lets say I have an array of 20 instances of MyClass - 7 of them would have a = 1, 13 of them would have a = 2
The desired output would be something like
Output = [7 1;13 2]
Thanks alot - Help is much appreciated

Try this
%% Create sample data
mc(20) = MyClass;
[mc(1:7).a] = deal(1);
[mc(8:20).a] = deal(2);
%% Desired output
edges = (1:2+1);
hc = histcounts( [mc.a], edges );
Output = [ reshape(hc,[],1), reshape(edges(1:2),[],1) ]
which shall output
ans =
7 1
13 2
This piece of code contains many "magic" numbers
- the number 20
- the numbers 7 and 13
- the values 1 and 2 of the property a
the value of edges must match the values of the property a
