This used to be called Tonys trick:
w1 = w1( ones( 1, 5 ) );
this is more standard
w1 = repmat( w1, 1, 5 );
PS. There is a good Getting Started!
--- Edit ---
>> w1=-0.5
w1 =
-0.5000
>> w1( ones( 1, 5 ) )
ans =
-0.5000 -0.5000 -0.5000 -0.5000 -0.5000
You need to experiment!
>> repmat( -0.11, 1, 5 )
ans =
-0.1100 -0.1100 -0.1100 -0.1100 -0.1100
