Basic Operators and Statements

1. Basic Operators

   • 

   • 

   • 

   • Array Operations: These operations treat matrices as arrays. They are also known as dot operations because the arithmetic operators are prefixed by a dot ()

   • If the matrix is complex-valued, then the operation of "array transpose" produces a complex-conjugate transposition.

   • The matrices will expand itself when the size of the matrices are not the same.

2. Indexing Operations

   • 

   • The operator "" can be used to generate sequences of numbers as well as to access certain row/column elements of amatrix.

   • Indexing a Matrix

     % Idexing a matrix
     x(rows, columns)

   • Using the fragment , we can generate numbers from a to c in b increments.

     • ex:

   • The fragment accesses elements of x beginning with index a in steps of b and ending at c.
