end

.zero(size) ⇒ MVector

Generates a zero vector of specified size.

Parameters:

  • size (Integer) —

    the size of the zero vector

Returns:

  • (MVector) —

Instance Method Details

#replace(other) ⇒ void

This method returns an undefined value.

Replaces the contents of this vector with the contents of another vector. This will not change the size of the current vector and will replace entries only up to the current size.

Parameters:

  • other (Vector<Numeric>, Array<Numeric>) —

    a vector (or array, or other indexable collection) with at least as many elements as this vector; its entries will replace this vector’s entries
