[Python 2.7] Quaternion Arithmetic Program

Hi guys, i'm currently learning how to program in Python and i've made a neat little script which can do arithmetic with quaternions

Code Select


from numpy import matrix
def quaternion(a,b,c,d):
    u = matrix('1.,0.,0.,0.;0.,1.,0.,0.;0.,0.,1.,0.;0.,0.,0.,1.')
    i = matrix('0.,1.,0.,0.;-1.,0.,0.,0.;0.,0.,0.,-1.;0.,0.,1.,0.')
    j = matrix('0.,0.,1.,0.;0.,0.,0.,1.;-1.,0.,0.,0.;0.,-1.,0.,0.')
    k = matrix('0.,0.,0.,1.;0.,0.,-1.,0.;0.,1.,0.,0.;-1.,0.,0.,0.')
    q = a*u+b*i+c*j+d*k
    return q
def printquaternion(q):
    a = q.item(0,0)
    b = q.item(0,1)
    c = q.item(0,2)
    d = q.item(0,3)
    q = "%s+%si+%sj+%sk"%(a,b,c,d)
    print q
