Hello,
In the documentation for cspice found here:
https://naif.jpl.nasa.gov/pub/naif/toolkit_docs/C/cspice/vadd_c.html
It says:
"vout may overwrite either v1 or v2"
"can overwrite either v1 or v2"
my question: Under what circumstance would vout overwrite v1 or v2? Can someone explain this wording?
Those words about overwrite are not mentioned under FORTRANspice or IDLspice online documentation.
Is this a bug in Cspice or why is this mentioned here?
I ask because when using the vadd_c in my code I have got some unpredicatble results and wondering if this
"overwriting" is causing the probem or my confusion.
The simple example provided by the documentation works fine for me though in my code.
Ideas anyone?
thanks
