Syntax |
E_(K:INT,N:INT or MODULE):VECTOR |
Summary |
canonical vector |
Description |
If N is an integer, this function returns the K-th canonical vector of the free module of rank N over the current ring. If N is a module, it returns the K-th canonical vector of N. |
Example |
Use R ::= Q[x,y]; E_(4,7); Vector(0, 0, 0, 1, 0, 0, 0) ------------------------------- M := Module([x^2,0,y^2],[x^3,x+y,y^3]); E_(2,M); Vector(0, 1, 0) ------------------------------- |
