Factor handbook » The language » Numbers » Vector operations

Vector/vector binary operations:
v+ ( u v -- w )
v- ( u v -- w )
v+- ( u v -- w )
v* ( u v -- w )
v/ ( u v -- w )
v^ ( u v -- w )

Vector unary operations:

vneg ( v -- w )

vabs ( v -- w )
vsqrt ( v -- w )
vfloor ( v -- w )
vceiling ( v -- w )
vtruncate ( v -- w )
normalize ( v -- w )

Vector/scalar and scalar/vector binary operations:

vneg ( v -- w )

v*n ( v n -- w )
n*v ( n v -- w )
v/n ( v n -- w )
n/v ( n v -- w )
v+n ( v n -- w )
n+v ( n v -- w )
v-n ( v n -- w )
n-v ( n v -- w )
v^n ( v n -- w )
n^v ( n v -- w )

Saturated arithmetic (only on Specialized arrays):

vs+ ( u v -- w )

vs- ( u v -- w )
vs* ( u v -- w )

Inner product and norm:

vdot ( u v -- x )

norm-sq ( v -- x )
l1-norm ( k -- x )
norm ( k -- x )
l-infinity-norm ( k -- x )
p-norm ( k p -- x )

Comparing entire vectors:

distance ( u v -- x )

v~ ( a b epsilon -- ? )
