Dear all,

I'm writing an object oriented piece of software in Matlab and I am looking for the following functionallity:

x = package.classobj1;
y = package.classobj2;

package.testfunction(x,y);

In the constructor of testfunction I save obj.var1=x, obj.var2=y but I also want to know the string name of these 2 variables. Eg: I want to know the string "x" and the string "y".

This would result in something like:
obj.var1name = SOMEFUNCTION(x);
obj.var2name = SOMEFUNCTION(y);

Does anyone know whether it is possible in Matlab to get this info?

Thanks

You could check to see if inputname works for objects

Thanks Donn, but unfortunately it doesn't work:

>> ocp = package.OCP(0.0, 1.0, 20);
>> inputname(ocp)
??? Error using ==> inputname
Scalar integer value required, but value is complex

Any other ideas?

Dear David!

Read the help of INPUTNAME. It works in functions only and replies the name of the n'th input argument in the caller - if the variable has a name at all. Anonymous variables are e.g. x(2), if x is 1:3.

Good luck, Jan

Hi David,

Is this what you are looking for?

classdef testfunction
properties
var1;
var1name;
var2;
var2name;
end
methods
function obj = testfunction(in1, in2)
obj.var1 = in1;
obj.var1name = inputname(1);
obj.var2 = in2;
obj.var2name = inputname(2);
end
end
end

>> value1 = 32

value1 =

32

>> value2 = 45

value2 =

45

>> object = testfunction(value1, value2)

object =

testfunction

Properties:
var1: 32
var1name: 'value1'
var2: 45
var2name: 'value2'

Methods

>>

Good Luck,

Donn
