Vectors, Matrices, and Multidimensional Arrays

MATLAB is designed to make operations on matrices as easy as possible. Most of the variables in MATLAB are considered as matrices. A scalar number is a 1x1 matrix and a vector is a Ixn (or nxl) matrix. Introducing a matrix is also done by an equality sign  

Note that elements of a row may be separated either by a space or a comma, and the rows may be separated by a semicolon or carriage return (i.e., a new line). Elements of a matrix can be called or replaced individually  

The transpose of a matrix results from interchanging its rows and columns. This can be done by putting a single quote after a matrix  

A very useful syntax in MATLAB is the colon operator that produces a row vector  

A very common use of the colon notation is to refer to rows, columns, or a part of the matrix
