WebEnter the initial filter weights, w ^ (0), as a vector or a scalar for the Initial value of filter weights parameter. When you enter a scalar, the block uses the scalar value to create a vector of filter weights. This vector has length equal to the filter length and all of its values are equal to the scalar value. port forward bell home hub 3000
