Scilab Function

colon - (:) colon operator

### Description

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

  j:kis the vector `[j, j+1,...,k]` (empty if `j>k` ).
  j:d:kis 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(:)=wfills the matrix `A` with entries of `w` (taken column by column if `w` is a matrix).
