README
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
- Install node-gyp
npm install node-gyp -g
- Build project files for your platform
node-gyp configure
- Generate
lpsolve.nodefile
node-gyp build
Testing
To test the module use the test task from gulp
gulp test
