Introduction:
Matlab is an application package that uses Numerical methods and technique to solve arithmetic
and logical operations. The Numerical method greatly expands the type of problems one can
address. Matlab is capable of handling large systems of equations, nonlinearities, and
complicated geometries that are not uncommon in engineering and science and that are
impossible to solve analytically with standard calculus. For one to be able to use Matlab to solve
systems of equation requires some knowledge from linear algebra, and other engineering
courses. The purpose of this project was to implement data search using important concept from
linear algebra.
Analysis:
First I created a random matrix
A
50 * 900
. Then I used the matlab command “vertcat” to create a
200 by 900 matrix. I define a vector
X
, vector
X
is the first column of A.
I then found the cosine
of the angle between X and columns of A, using the dot product formula. The result was 900
