Hi,

Thank you for this fantastic library.

I have a large amount of data to process. Does this library thread safe in the sense that I can launch multiple queries from different threads?

Thanks,

Thanks you. It should be after the interpolator is constructed. The data to interpolate is copied internally, then each interpolator can pre-compute some additional parameters that depend on data that will be shared by calls to the operator(...) function but these should all be read only. Any intermediate values computed during the interpolation should be written to local variables.

It does not store the index to the previously used data points to speed up the search during the next call.

But... I don't do a ton of threaded code and I have not tested it for this, so its possible.
