## Elementary row operations

### Description

These are elementary operations for a matrix. They do not presume a square matrix and will work on any matrix. They use R's internal row addressing to function.

### Usage

swaprows(m, row1, row2)

replacerow(m, row1, row2, k)

scalerow(m, row, k)


### Arguments

 m a matrix row1 a source row row2 a destination row k a scaling factor row a row to modify

### Details

replacerow replaces one row with the sum of itself and the multiple of another row. swaprows swap two rows in the matrix. scalerow scales all enteries in a row by a constant.

### Value

the modified matrix
