If you're a scientist or an engineer interested in learning scientific computing, this is the place to start.

In this course, you'll learn to write your own useful code to perform impactful scientific computations. Along the way, your understanding will be tested with periodic quizzes and exercises.

Topics covered in this course include arrays, plotting, linear equations, symbolic computation, scientific algorithms, and random variables. You’ll also be exposed to popular Python packages like NumPy, Matplotlib, SciPy, and others. In the last part of the course, the application section will test your ability to recall and apply the tools you have studied into newly learned scientific concepts.

At the end of this course, you'll be equipped with the tools necessary for everyday scientific computation.

Python for Scientists and Engineers

The linear algebra module of NumPy, `linalg`, provides a number of functionalities, including the ability to solve systems of linear equations. This is done using the matrix method. 

Suppose we have the following system of linear equations:

<center>

$2x+3y+z=17$

$3x+4y+2z=25$ 

$x+y-z=6$
</center>

We need to convert these to the form $AX=b$ and solve the equation for $X$.

<center>

$\begin{bmatrix}2 & 3 & 1 \\3 & 4 & 2 \\1 & 1 & -1 \end{bmatrix} \begin{bmatrix}x \\y \\z \end{bmatrix} = \begin{bmatrix}17 \\25 \\6 \end{bmatrix}$

</center>

In this lesson, you will learn how to build and solve a system of linear equations in Python.
