This pull request adds documentation for builtin intersect function
## `intersect`-Function
This is a generic function, extended from the intersect function in the base
package. The elements of intersect(x,y) are those elements in x and in y.
The original definition is preserved in the case that x and y are vectors of
the same mode.
### Usage
```r
intersect(x, y)
```
### Arguments
| Name | Type | Default | Description |
| :------ | :------------- | -------- | :---------- |
| X | Matrix[Double] | -- | a set of matrix A |
| Y | Matrix[Double] | -- | a set of matrix B |
### Returns
| Type | Description |
| :------------- | :---------- |
| Matrix[Double] | intersection matrix, set of intersecting items|
### Example
```
intersect = function(Matrix[Double] X, Matrix[Double] Y)
return(Matrix[Double] A)
{
X = rand (rows = 50, cols = 10)
Y = X %*% rand(rows=ncol(X), 1)
intersect(X,Y)
```
