minus

PURPOSE

MINUS Substraction of two TT/MPS block-mu tensors.

SYNOPSIS

function z = minus( x, y )

DESCRIPTION

MINUS Substraction of two TT/MPS block-mu tensors.
   Z = MINUS(X,Y) substracts two TT/MPS tensors. The rank of the resulting
   tensor is the sum of the individual ranks.

   See also PLUS, UMINUS.

CROSS-REFERENCE INFORMATION

This function calls:

plus PLUS Addition of two TT/MPS tensors.
uminus UMINUS Unary minus.
