[Pkg-octave-devel] Bug#731992: octave-statistics: princomp fails with nargout < 2

[Kacper Gutowski]

Package: octave-statistics
Version: 1.2.2-1
Severity: normal
Tags: upstream patch

The princomp function as included in octave-statistics always throws an
error in context where only first return value is expected:

hyper% octave -q --no-init-file
warning: function /usr/share/octave/packages/statistics-1.2.2/fstat.m shadows a core library function
octave:1> princomp(rand(10,2))
error: 'r' undefined near line 103 column 48
error: invalid limit value in colon expression
error: evaluating argument list element number 1
error: called from:
error:   /usr/share/octave/packages/statistics-1.2.2/princomp.m at line 103, column 9
octave:1>

As far as I can tell this is a trivial bug caused by the fact that 'r'
is only calculated if nargout > 1 and not needed otherwise so it can be
fixed with the simple patch attached.
