Are you aware that the notation, you have invented, is not clear or unique? What exactly does the smaller than operator do with a string? What exactly is (-inf-6.95] ?
Do you mean: Moyenne is > -Inf and small or equal -6.95?

Can't. Comparison operations always return logical 0 (false) where A or B have NaN elements.
Best you can do is test if result isfinite or not. See
doc isfinite % and friends for more information
ADDENDUM
OK, w/ the additional background try
Ayup...
moyenne<=-6.95
would give everything <= the breakpoint into that region, up to as large a negative value as can be represented. If the model can/does generate -Inf, that will have to be special-cased.
Jan's guess wasn't too far off, looks like
if sign(moyenne)*isinf(moyenne)==-1 | moyenne<=-6.95 % handle -Inf, too...
should do it. The first tests for -Inf and the other takes the case is finite but < than the breakpoint.
Do the similar thing on an unbounded upper bin as well.
