Matrices
As seen in the previous chapter, a matrix consists of vectors as
columns: A=[a1 a2 an]
For an mn matrix, its structure is
Two matrices are equal iff they have the same size and their
corresponding entries are equal
Sum of two matrices is just

Eigenvalues and Eigenvectors
For an nn matirx A, if there is a nonzero vector x such that Ax=x
for some scalar , then is an eigenvalue of A, and x is the
eigenvector corresponding to
If we view A as a mapping, Ax=x means that the mapping A acting
on x
Q1. Let 3 = 1 and 6= 1.
Find the value of 2011 + 1997 + 1.
Answer. Since 3 = 1 we have
2011 + 1997 + 1
= 3670+1 + 3665+2 + 1
= + 2 + 1 .
Now we also have
0 = 3 1 = ( 1)( 2 + + 1) .
Since 6= 1, 2 + + 1 = 0. So
2011 + 1997 + 1 = 0 .

Inner Product
For two vectors u, v in Rn, the inner product is defined as
v1

It is obvious that uTv= vTu
From inner product, we can define other attributes of a vector

Vectors
A real number is a point on the real line R
To describe a point on a plane R2, we use two numbers, e.g., (3,-1)
In fact, this is just an expression of a point using rectangular
