why r= stem(5/2) = 174.0181 ?

Hello, See the next line

r= stem(5/2); r= 174.0181

Note: The value of 'r' changes slightly ( & randomly), over time. Question: Yes, it shows the plot correctly (i.e. stem of 5/2), but I wonder why the value of 'r' is such? I will appreciate your time answering this!

Regards

The result of

r = stem(5/2);

is a plot handle. If you want to understand what it actually is, type:

get(r)

and see what it returns.

Note: the return from stem() and other graphics routines changed a lot in R2014b

Upon this, get(r) tells 'Invalid handle object'.

In R2017a this:

r = stem(5/2)

returns:

r = 

    Stem with properties:

                Color: [0.0000e+000 447.0000e-003 741.0000e-003]
            LineStyle: '-'
            LineWidth: 500.0000e-003
               Marker: 'o'
           MarkerSize: 6.0000e+000
      MarkerFaceColor: 'none'
            BaseValue: 0.0000e+000
                XData: 1.0000e+000
                YData: 2.5000e+000

    Show all properties

Using ‘get(r)’ would have returned all the properties.

I no longer have access to R2014a and earlier versions, so I cannot explore that.

In my experience, the get function with the correct argument has always returned the properties of the object that created it.
