Return empty matrix when linspace called with 0 points (bug #45820) * NEWS: Announce change. * data.cc (Flinspace): Verify input N is scalar. Verify inputs BASE, LIMIT are scalar/vectors. Add BIST tests for input validation, complex values, class of output, Matlab compatibility. Clarify documentation about vector inputs. * CMatrix.cc, CRowVector.cc, dMatrix.cc, dRowVector.cc, fCMatrix.cc, fCRowVector.cc, fMatrix.cc, fRowVector.cc: Return empty matrix when N < 1.

  ** mkfifo now interprets the MODE argument as an octal, not decimal, integer.
     This is consistent with the equivalent shell command. 
 
+ ** linspace now returns an empty matrix if the number of requested points
+    is 0 or a negative number.  This change was made to be compatible with
+    Matlab releases newer than 2011.  In addition, Octave no longer supports
+    matrix inputs for A or B.

  ** The griddata function no longer plots the interpolated mesh if no output
     argument is requested, instead the vector or array of interpolated values
     is always returned for Matlab compatibility.
