Dear Przemek,

thanks for your report and help to make the interval package better!

The “mpfr_to_string_d” function is part of the interval package and a
wrapper/interface to GNU MPFR functions from inside Octave. It is used
internally by the package and gets compiled during package installation.
Not being able to call the function means that something is wrong with
your paths. Did you upgrade from an earlier Octave version without
recompilation of the package?

I tried to reproduce: Installed Fedora 23 together with Octave 4.0.0.
After “dnf install mpfr-devel octave-devel” I could install the interval
package.

I was able to use the package like this:
>> pkg load interval
>> infsupdec (1)
ans = [1]_com
>> infsupdec ("[Empty]")
ans = [Empty]_trv

Your error message indicates that x is an unsupported data type.
Parameters to the infsupdec constructor should be matrices, cell arrays
or strings. If you need further help, please create a bug report with
detailed instructions to reproduce the error message here:
