JarCastinggl-mat4 
Part of a fork of @toji's gl-matrix split into smaller pieces: this package contains glMatrix.mat4.
Usage
mat4 = require('gl-mat4')
Will load all of the module's functionality and expose it on a single object. Note that any of the methods may also be required directly from their files.
For example, the following are equivalent:
var scale = require('gl-mat4').scale
var scale = require('gl-mat4/scale')

adjoint(out:mat4, a:mat4)
Calculates the adjugate of a mat4
clone(a:mat4)
Creates a new mat4 initialized with values from an existing matrix
copy(out:mat4, a:mat4)

fromQuat(out:mat4, q:quat4)
Creates a matrix from a quaternion rotation.
fromRotation(out:mat4, rad:number, axis:vec3)
Creates a matrix from a given angle around a given axis This is equivalent to (but much faster than):
mat4.identity(dest);
mat4.rotate(dest, dest, rad, axis);
fromRotationTranslation(out:mat4, q:quat4, v:vec3)
Creates a matrix from a quaternion rotation and vector translation. This is equivalent to (but much faster than):
mat4.identity(dest);
mat4.translate(dest, vec);
var quatMat = mat4.create();
quat4.toMat4(quat, quatMat);
mat4.multiply(dest, quatMat);
fromScaling(out:mat4, v:vec3)
Creates a matrix from a vector scaling. This is equivalent to (but much faster than):
mat4.identity(dest);
mat4.translate(dest, dest, vec);
fromTranslation(out:mat4, v:vec3)
Creates a matrix from a vector translation. This is equivalent to (but much faster than):
mat4.identity(dest);
mat4.translate(dest, dest, vec);
