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
