Would it be possible to have the interp1 function return warnings in its own namespace to make suppressing these warnings easier?
When reviewing logs of large data analysis, these warnings can be repetitive and distracting.  I can disable all warnings, but this seems like overkill and more granularity would be helpful.

x=[1 1 1 2 3 4];
y=[10 9 12 15 17 18];
interp1(x,y, [1 1.1 1.2 2.1 3.1 3.9])

Returns:

warning: interp1: multiple discontinuities at the same X value
warning: called from
    interp1 at line 242 column 11

ans =

   12.000   12.300   12.600   15.200   17.100   17.900

It would be nice to be able disable this warning with a command like:

warning("off","interp1:badInput")

I think this can be done just by changing line 242 of interp1.m
from:

warning ("interp1: multiple discontinuities at the same X value");

to:

warning ("interp1:badInput","interp1: multiple discontinuities at the same X value");

This likely could be applied to other functions like interp2 as well.  Is there a reason that these functions shouldn't use their own namespace for warnings?
