**Goal:**

Understanding elementary matrix algebra, and the
determinant and inverse of a matrix. Understanding a linear system of
equations both as a set of lines/(hyper)planes in x-space and in the space
of column vectors. Understanding that f(x)=Ax is a linear function/mapping in x, (like the projection Px onto a given matrix, the rotation Rx, etc).

Understand the extension of the number system to complex numbers, and the algebra of these.

Understanding the definition of a graph having a tangent, the
concept of "linearization" of a function close to a given point, and the
related definition of the derivative of a function.

**Reading:**

AMB&S chap. 20 - 23.

**Excercises:**

**23.1**, **23.2**, 23.6, 23.7

**Goal:**

To learn relevant matlab notation and syntax related to elementary matrix calculation, and to get to better understand the matrix algebra through matlab.

**Reading:**

**Exercises:**

L=Lecture, S=Studio, G=Group work

L1: More on linearization, derivative.

S1: Linear systems of equations. Gaussian elimination. Row pivoting. The determinant. Inverse matrix. Geometric interpretation. Linear algebra using Matlab. Work on project f(x)=0.
