The header type SparseMonomialVectorExpression is a member of the class HeaderType. Each object of class SparseMonomialVectorExpression is called a sparse monomial vector expression. Each sparse monomial vector expression is also a member of class Expression.
More general types (whose methods may also apply) :
SparseMonomialVectorExpression -- a type of Expression representing a sparse monomial vector.
The difference between this and SparseVectorExpression is that the basis vectors are treated like variables for printing purposes.
