Description

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

.<op> used in cunjunction 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. Two or more decimal points at the end of a line causes the following line to be a continuation.

Examples

1.345
x=[1 2 3];x.^2 .*x // a space is required between 2 and dot
[123,..
 456]
