The functions that allow displaying components of vector quantities are: Vec3(x,y,z) in Flux3D and Vec2(x,y) in Flux2D.
Ex. In order to display the first component of B the formula is: Vec3(Comp(1,B),0,0)
All the functions for treatment of the vectors are gathered in the table below.
| ModV(v) | Vector modulus of the vector expression v |
| Comp(i,v) | Component i of the vector expression v |
| PVec(v1,v2) | Vector product of 2 real vector expressions |
| Vec2(x,y) | 2D vector built starting from the real expressions x and y |
| Vec3(x,y,z) | 3D vector built starting from the real expressions x, y and z |
| Mod(x) | General modulus of the expression x: Mod(x)=ModV(ModC(x)) |
