it means exactly what it says: you passed a matrix as an input to a function 
that expects a set of strins as input.
the function tried to convert the matrix to a string, but, as that is most 
likely not what you intended to do, it
gave you a warning to let you now what happened.

It depends on what your application does and where the incorrenct input was 
passed.

you can turn off all warnings or one specific warning at a time, see the manual 
section about the "warning" 
command to find out how.

first I would try to find out where the warning comes from, for example by 
doing:

  warning ("error")

so that the warning will be changed to an error, and Octave will sto and tell 
you where it has occurred.
