colon - (:) colon operator

Colon symbol : can be used to form implicit vectors. (see also linspace , logspace )

j:k is the vector [j, j+1,...,k] (empty if j>k).

j:d:k is the vector [j, j+d, ..., j+m*d]

The colon notation can also be used to pick out selected rows, columns and elements of vectors and matrices (see also extraction , insertion )

A(:) is the vector of all the elements of A regarded as a single column.

A(:,j) ys the j-th column of A

A(j:k) is [A(j),A(j+1),...,A(k)]

A(:,j:k) is [A(:,j),A(:,j+1),...,A(:,k)]

A(:)=w fills the matrix A with entries of w (taken column by column if w is a matrix).
