### sub()

Examples
```PVector v1, v2;

void setup() {
smooth();
noLoop();
v1 = new PVector(40, 20, 0);
v2 = new PVector(65, 70, 0);
}

void draw() {
ellipse(v1.x, v1.y, 12, 12);
ellipse(v2.x, v2.y, 12, 12);
v2.sub(v1);
ellipse(v2.x, v2.y, 24, 24);
}```

```PVector v;

void setup() {
smooth();
noLoop();
v = new PVector(65, 70, 0);
}

void draw() {
ellipse(v.x, v.y, 12, 12);
ellipse(40, 20, 12, 12);
v.sub(40, 20, 0);
ellipse(v.x, v.y, 24, 24);
}```

```PVector v1, v2;

void setup() {
smooth();
noLoop();
v1 = new PVector(65, 70, 0);
v2 = new PVector(40, 20, 0);
}

void draw() {
ellipse(v1.x, v1.y, 12, 12);
ellipse(v2.x, v2.y, 12, 12);
PVector v3 = PVector.sub(v1, v2);
ellipse(v3.x, v3.y, 24, 24);
}```
Description

Subtracts x, y, and z components from a vector, subtracts one vector from another, or subtracts two independent vectors. The version of the method that substracts two vectors is a static method and returns a PVector, the others have no return value -- they act directly on the vector. See the examples for more context.

Syntax
`vec.sub(x,y,z)`

`vec.sub(v)`

`PVector.sub(v1,v2)`

Parameters
vec any variable of type PVector float: the x component of the vector float: the y component of the vector float: the z component of the vector PVector: the x, y, and z components from a PVector object PVector: the x, y, and z components from a PVector object PVector: the x, y, and z components from a PVector object
Returns None or PVector
