## Uncompress a Blob object

### Description

compression is one of 0 = no, 1 = zlib, 2 = np-linear, 3 = np-slof, 4 = np-pic, 5 = np-linear + zlib, 6 = np-slof + zlib, 7 = np-pic + zlib

### Usage

    uncompressVec(x, type)

### Arguments

`x` | (Blob object)
`type` | (integer) must either be 5L or 6L to indicate linear and short logged float compression, respectively.
