Requirements
------------

[](#requirements)

NumPhp supports PHP 7.2, 7.3 7.4 and 8.0.

---

Install
-------

[](#install)

composer require sciphp/numphp

```

---

Basic usage
-----------

[](#basic-usage)

```
use SciPhp\NumPhp as np;

$m = np::ar(
  [[ 1, 0, 0],
   [ 0, 1, 0],
   [ 0, 0, 1]]
)->dot(42);

echo "m.42 =\n$m";
```

will output:

```
m.42 =
[[ 42,  0,  0 ],
 [  0, 42,  0 ],
 [  0,  0, 42 ]]
