fibomat.linalg.vectors.vector module¶

class fibomat.linalg.vectors.vector.Vector(*args, **kwargs)[source]¶

Bases: fibomat.linalg.vectors.vector_base.VectorBase[float]

__init__(*args, **kwargs)[source]¶

property angle_about_x_axis: float¶

Angle between vector and positive x axis (angle will be in [0, 2pi]).

Access:: get
Returns:: float
Raises:: RuntimeError: Raised if self is null vector.

close_to(other: Iterable[fibomat.linalg.vectors.vector_base.T]) → bool¶

Checks if other is close to self component wise.

Args:: other (Vector, Iterable[float]): other vector(like)
Returns:: bool

count(value) → integer – return number of occurrences of value¶

cross(other: Iterable[fibomat.linalg.vectors.vector_base.T]) → fibomat.linalg.vectors.vector_base.T¶

Cross product in 2d.

a x b = a.x * b.y - a.y * b.x

a = self, b = other

Args:: other(VectorLike): other vector
Returns:: T

dot(other: Iterable[fibomat.linalg.vectors.vector_base.T]) → fibomat.linalg.vectors.vector_base.T¶

Calculate dot product with other vector.

Args:: other(VectorLike): other vector
Returns:: float

index(value[, start[, stop]]) → integer – return first index of value.¶

Raises ValueError if the value is not present.

Supporting start and stop arguments is optional, but recommended.

property length: fibomat.linalg.vectors.vector_base.T¶

Length (magnitude) of vector.

Access:: get
Returns:: T

property mag: fibomat.linalg.vectors.vector_base.T¶

Magnitude of vector (short form of VectorBase.magnitude).

Access:: get
Returns:: T

property magnitude: fibomat.linalg.vectors.vector_base.T¶

Magnitude of vector.

Access:: get
Returns:: T

mirrored(mirror_axis: Iterable[fibomat.linalg.vectors.vector_base.T]) → fibomat.linalg.vectors.vector_base.SelfT¶

Return a mirrored version of the vector.

Args:: mirror_axis (VectorLike): mirror axis
Returns:: Vector

normalized() → fibomat.linalg.vectors.vector_base.SelfT¶

Create a new vector with same Vector.phi but Vector.r = 1.

Returns:: SelfT

normalized_to(length: fibomat.linalg.vectors.vector_base.T) → fibomat.linalg.vectors.vector_base.SelfT¶

Create a new vector Vector.phi but Vector.r = length.

Args:: length (float): new length of vector
Returns:: Vector

property phi: float¶

Angular component of vector (angle between vector and x axis in radiant between -pi and pi).

Access:: get
Returns:: float

projected(other: Iterable[fibomat.linalg.vectors.vector_base.T]) → fibomat.linalg.vectors.vector_base.SelfT¶

Project other onto self. https://en.wikibooks.org/wiki/Linear_Algebra/Orthogonal_Projection_Onto_a_Line

Args:: other:
Returns:: Vector

property r: fibomat.linalg.vectors.vector_base.T¶

Access:: get
Returns:: float

rotated(theta: float, origin: Optional[Iterable[fibomat.linalg.vectors.vector_base.T]] = None) → fibomat.linalg.vectors.vector_base.SelfT¶

Return a rotated copy the vector around center with angle theta in math. positive direction.

Args:: theta (float): rotation angle in rad origin (VectorLike): rotation center, default to [0., 0.]
Returns:: Vector

property x: fibomat.linalg.vectors.vector_base.T¶

X component the vector

Access:: get
Returns:: T

property y: fibomat.linalg.vectors.vector_base.T¶

X component the vector

Access:: get
Returns:: T
