dot - (.) symbol

### Calling Sequence

  `123.33`
  `a.*b`
  `[123,..`
  `456]`

### Description

  .

  Dot is used to mark decimal point for numbers : 3.25 and 0.001

  .<op>

  used in conjunction with other operator symbols (`* / \ ^ '`) to form other operators. Element-by-element multiplicative operations are obtained using `.* , .^ , ./ , .\` or `.'`. For example, C = A ./ B is the matrix with elements c(i,j) = a(i,j)/b(i,j). Kronecker product is noted .*. . Note that when dot follows a number it is alway prt of the number so 2.*x is evaluated as 2.0*x and 2 .*x is evaluated as (2).*x

  ..

  Continuation mark. Two or more decimal points at the end of a line (or followed by a comment) causes the following line to be a continuation.

  Continuation lines are handled by a preprocessor wich builds a long logical line from a given sequence of continuation lines. So the continuation marks can be used to cut a line at any point.

### Examples

    //decimal point
    1.345

    //used as part of an operator
    x=[1 2 3];x.^2 .*x // a space is required between 2 and dot

    // used to enter continuation lines
    T=[123,..//first element
       456] //second one

    a="here I start a very long string...  //but I'm not in the mood of continuing
         - and here I go on"
    y=12..
    45
