nodesolve

Use LP Solve 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
