klampt.math.vectorops module

Allows treating tuples/lists as vectors

klampt.math.vectorops.add(*items)

Adds one or more vectors.

klampt.math.vectorops.madd(a, b, c)

Return a+c*b where a and b are vectors.

klampt.math.vectorops.sub(a, b)

Subtract a vector b from a, or subtract a scalar

klampt.math.vectorops.mul(a, b)

Multiply a vector either elementwise with another vector, or with a scalar.

klampt.math.vectorops.div(a, b)

Elementwise division with another vector, or with a scalar.

klampt.math.vectorops.maximum(a, b)

Elementwise max

klampt.math.vectorops.minimum(a, b)

Elementwise min

klampt.math.vectorops.dot(a, b)

Dot product.

klampt.math.vectorops.normSquared(a)

Returns the norm of a, squared.

klampt.math.vectorops.norm(a)

L2 norm

klampt.math.vectorops.unit(a, epsilon=1e-05)

Returns the unit vector in the direction a. If the norm of a is less than epsilon, a is left unchanged.

klampt.math.vectorops.norm_L2(a)

L2 norm

klampt.math.vectorops.norm_L1(a)

L1 norm

klampt.math.vectorops.norm_Linf(a)

L-infinity norm

klampt.math.vectorops.distanceSquared(a, b)

Squared L2 distance

klampt.math.vectorops.distance(a, b)

L2 distance

klampt.math.vectorops.cross(a, b)

Cross product between a 3-vector or a 2-vector

klampt.math.vectorops.interpolate(a, b, u)

Linear interpolation between a and b
