## dojitter

### Description

This function adds a random uniform vector of the same length as the input to modify the input.

### Usage

    dojitter(x, amount = 0)

### Arguments

`x` | a vector to be jittered (e.g. a gridpoint vector).
`amount` | a value of how much to jitter the vector x.

### Details

The function creates `length(x)` samples from a uniform[-amount,amount], and adds these to the original vector x. If amount=0, the new vector jx is the same as the original vector.

### Value
