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..
