Two consecutive dots does not comprise a valid MATLAB construction. This message might indicate a typographical error. For example, if you meant to specify the ellipsis (...) line continuation operator, but accidentally specified two dots instead of three. Or, if you did not insert a space before the ellipsis, when needed.

For example, in processing the following line, Code Analyzer generates this message because the first dot is evaluated as a decimal point associated with the 3, leaving two consecutive dots:

x = 3...

Fix the code by adding or removing a dot, or by inserting a space before the ellipsis (...).
