Set X_i=(x_i (1),x_i (2),⋯,x_i (n)) as the behavior sequence of factor X_i, D_1 as the sequence operator, and X_i D_1=(x_i (1)d_1,x_i (2)d_1,⋯,x_i (n)d_1), where x_i (k)d_1=x_i (k)/x_i (1); x_i (1)≠0, k=1,2,⋯,n, then D_1 is A: A. Initial valued operator B: B. Averaging operator C: C. Interval valued operator D: D. Invert operator

Operator: ( ) A: An operator is a DNA region that is working with promoter for genes to express. B: An operator is a DNA region at 5’ of a gene for a repressor to bind to prevent gene expression. C: An operator is a repressor protein to help genes to express. D: An operator is a repressor protein to inhibit genes to express.

It is for this reason that Laplace’s operator(拉氏算子) is sometimes written as ▽2(read triangle squared).

1、In MATLAB, the right division operator (/) and the left division operator (\) are equivalent.

The OR (||) operator _________.

Who is the operator?
