matrix7 1.2.0
Matrix and Vector Manipulation library

# Matrix7

a library in pure python3 that allows you to use matrices and vectors easily

## Setup

```
sudo pip install matrix7
```

## How to use

#### Declarations

```python
from matrix7 import Matrix, Vector

a = Matrix([
    [1,2,3,4,5,6,7],
    [101,102,103,104,105,106,107],
    [201,202,203,204,205,206,207],
])

b = Vector( [2,4,7,9] )

c = Vector( [2,4,7,9] , transpose = True )
```

#### printing

- `print(a)` :

```text
|   1.00   2.00   3.00   4.00   5.00   6.00   7.00 |
| 101.00 102.00 103.00 104.00 105.00 106.00 107.00 |
| 201.00 202.00 203.00 204.00 205.00 206.00 207.00 |
```

- `print(b)` :

```text
|   2.00 |
|   4.00 |
|   7.00 |
|   9.00 |
```

- `print(c)` :
```text
|   2.00   4.00   7.00   9.00 |
```

#### properties

```python
a.size    # (nb lines, nb cols)
a.trace   # only for nxn matricies
a.raw     # matrix or vector in normal python list format
a.gravity # only for vectors
```

#### operations

- normal python operations are used
- Matrix or Vector object is returned
- regular matrix/vector calculation rules apply

```python
c = a + b
c = a - b
c = a * b
```

#### trasponse of matrix or vector

```python
a.transpose()
```

#### generation

```python
# vector containing 6 threes
vect = Vector.gen(6, 3)

# 3x4 matrix of zeroes
mat = Matrix.gen(3, 4, 0)
```

#### navigation

```python
# matrix line 0 (Vector) or vector element (int, float ..etc)
a[0]
# matrix column 0 (Vector)
a(0)
# matrix element (0,0) (int, float ..etc)
a[0][0]
```
appengine-clean 0.1.6
Clean old AppEngine versions
Keywords: utility,miscellaneous,library

# appengine_clean
Clean up old versions of AppEngine instances to avoid the dreaded "Your app may not have more than 210 versions. Please delete one of the existing versions before trying to create a new version" error

## Usage:

First, let's do a dry-run. Run the following to keep 15 versions of each module around:
```
appengine-clean my-project-id 15 --dry-run
```

If you're happy with the result of the dry-run, let's delete:

```
appengine-clean my-project-id 15 --force
```
