ints) A common representation of data uses matrices and vectors, so it is helpful
to familiarize ourselves with linear algebra notation, as well as some simple operations.
Define a vector ♬ to be a column vector. Then, the following properties hold:
• cu with c some constant, is equal to a new vector where every element in cv is equal
to the corresponding element in & multiplied by c. For example, 2
2
=
● √₁ + √2 is equal to a new vector with elements equal to the elementwise addition of
₁ and 2. For example,
問
2+4-6

The above properties form our definition for a linear combination of vectors. √3 is a
linear combination of √₁ and √2 if √3 = a√₁ + b√2, where a and b are some constants.
Oftentimes, we stack column vectors to form a matrix. Define the column rank of
a matrix A to be equal to the maximal number of linearly independent columns in
A. A set of columns is linearly independent if no column can be written as a linear
combination of any other column(s) within the set. If all…
