class TFoamVect: public TObject

 Default constructor for streamer

 User constructor creating n-dimensional vector
 and allocating dynamically array of components

 Copy constructor

 Destructor

 [] is for access to elements as in ordinary matrix like a[j]=b[j]
 (Perhaps against some strict rules but rather practical.)
 Range protection is built in, consequently for substitution
 one should use rather use a=b than explicit loop!

 unary multiplication operator *=

 unary addition operator +=; adding vector c*=x,

 unary subtraction operator -=

 addition operator +; sum of 2 vectors: c=a+b, a=a+b,
 NEVER USE IT, VERY SLOW!!!

 subtraction operator -; difference of 2 vectors; c=a-b, a=a-b,
 NEVER USE IT, VERY SLOW!!!
