Use [LP Solve](http://lpsolve.sourceforge.net) from NodeJs. This module uses LP Solve 5.5.2

# Usage

**First of all, all the functions are 0-index instead of 1-index like in lpsolve**

Install the module using npm

````

npm install nodesolve

````

For more information see the JSDoc

# Build from source

1. Install node-gyp

```` 

npm install node-gyp -g

````

2. Build project files for your platform

````

node-gyp configure

````

3. Generate `lpsolve.node` file

````

node-gyp build

````

# Testing

To test the module use the test task from gulp

````

gulp test

````
