Matrix Notation. Here, we describe how symbols are used on the Stat Trek web site to represent vectors, matrices, and other matrix algebra entities. Vectors. Bold-face, lower-case letters refer to vectors; and italic lower-case letters refer to vector elements. For example,

In linear algebra, for example, the standard notation is just capital latin letter for matrices and lowercase latin letter for vectors (opinions divide whether we should add an arrow above a vector). If you want to write in bold, you can use the same approach as with "blackboard bold", e.g. $\mathbb A$ ( \mathbb A ).

The matrix A is said to represent the linear map f, and A is called the transformation matrix of f. For example, the 2×2 matrix = [] can be viewed as the transform of the unit square into a parallelogram with vertices at (0, 0), (a, b), (a + c, b + d), and (c, d).

A square matrix has the same number of rows and columns, \(m=n. \) The elements of a square matrix \(\boldsymbol{A}_{n\times n} \) where the subscripts are equal \(\left( a_{11}, a_{22}, \cdots, a_{nn}\right) \) are called the matrix main diagonal.

i want to create *alphabetic matrix* like this [ a b c d d e f g h i j k } so how we create it???
