1. Introduction
The sequence 1,1,2,3,5..., got its name as name as Fibonacci sequence by the Famous Mathematics Francois Edouard Lucas in 1876 [7].
Lucas also discovered a new Fibonacci like sequence with different initial condition call it, Lucas Sequence
with initial condition
,
In 1965 Hoggatt, V.E. [5] has defined Lucas polynomials by recurrence relation.
where
 | (1.1) |
The first few Lucas polynomials are
In this paper, we are using the pair of sequence {Gn} and {Pn} for which,
 | (1.2) |
 | (1.3) |
where k is any positive integer. k= 0, 1, 2, 3...
Using the equation (1.1) and (1.2) and made a rising diagonal function and descending Diagonal Functions.
2. Sequence {Gn} and {Pn}
We have the pair of sequence {Gn} and {Pn} for which,
The first few terms of the sequence {Gn} are
 | (2.1) |

3. Rising Diagonal Function
Consider the rising diagonal function of x, Un (x), un (x) for (2.1) and (2.2) respectively,
 | (3.1) |
 | (3.2) |
Now, we define
 | (3.3) |
from equation (3.1), (3.2) and (3.3) we get the following theorem:
Theorem (1). If Un (x) and un(x) are rising diagonal functions of x for sequence {Gn} and {Pn} respectively, than for, 
 | (3.4) |
Proof can be obtained by PMI’s method so it is obvious.
Special Case-I
If Un (x) and un(x) are rising diagonal functions of x f sequence {Gn} and {Pn} respectively, than for n=3, n=4.

4. Descending Diagonal Function
From (2.1) and (2.2), the descending diagonal function of x, Qi(x), qi(x) are
 | (4.1) |
 | (4.2) |
Now, we define
 | (4.3) |
from (4.1), (4.2) and (4.3) we get for
.
 | (4.4) |
 | (4.5) |
from (4.4) and (4.5) we get the following theorem:
Theorem (2). If Qn(x) and qn(x) are descending diagonal function of x for Sequence {Gn} and {Pn} respectively, than for

5. Generating Matrix
For the sequence {Gn} defend in equation (1.1) we consider the matrix

Proof. For sequence {Gn}, we have
Since, determinant of matrix A is -1, therefore,

Form equation (3.5.2) and (3.5.3), we get
Since 
After multiplying the matrices and equating the corresponding elements, we get

After multiplying the matrices and equating the corresponding elements, we get
6. Generating Matrix
For the sequence {Pn} defend in equation (1.1) we consider the matrix
 | (6.1) |
since, the elements of this matrix are the members of the sequence of Fibonacci polynomials. We call this matrix as Fibonacci Matrix.
