Overview
Linear algebra is a branch of mathematics concerning linear equations such as:
:<math>a_1x_1+\cdots +a_nx_n=b,</math>
Vector
Matrix
M m x n
m - rows
n - columns.
Norm
Polynomial
Organizatorium
- Scalar
- Matrix - two-dimensional array (rows, columns)
- Vector - a matrix with just one column.
- 1-indexed and 0-indexed vectors.
- Linear map.
- Vector space.
- Point in a multi-dimensional vector space, equivalent with a vector in the same multidimensional vector space.
