123.33 a.*b [123,.. 456]
Dot is used to mark decimal point for numbers : 3.25 and 0.001
used in conjunction with other operator symbols (
*/ \ ^ ') to form other operators. Element-by-element multiplicative operations are obtained using
.* , .^ , ./ , .\or
.'. For example,
C = A ./ Bis 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 always a part of the number so
2.*xis evaluated as
2 .*xis evaluated as
Continuation mark. Two or more dots 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 which builds a long logical line from a sequence of continuation lines. So the continuation marks can be used to cut a line at any point.
The following function
is equivalent to:
The logical line formed by physical line 3 and physical line 4 is built as if it was entirely written in the physical line 4 while physical line 3 would be empty. This is done this way because continuation marks can be put anywhere even inside an expression.
