Constructors

Mat3([List<double>? elements])

Properties

elements ↔ List<double>

A vector of length 9, containing all matrix elements.

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

copy(Mat3 matrix) → Mat3

Copy another matrix into this matrix object.

e(int row, int column, [double? value]) → double?

Get an element in the matrix by index. Index starts at 0, not 1!!! @param value If provided, the matrix element will be set to this value.

getTrace([Vec3? target]) → Vec3

Gets the matrix diagonal elements

identity() → void

Sets the matrix to identity @todo Should perhaps be renamed to setIdentity() to be more clear. @todo Create another function that immediately creates an identity matrix eg. eye()

mmult(Mat3 matrix, [Mat3? target]) → Mat3

Matrix multiplication @param matrix Matrix to multiply with from left side.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

reverse([Mat3? target]) → Mat3

reverse the matrix @param target Target matrix to save in. @return The solution x

scale(Vec3 vector, [Mat3? target]) → Mat3

Scale each column of the matrix

setRotationFromQuaternion(Quaternion q) → Mat3

Set the matrix from a quaterion

setTrace(Vec3 vector) → void

Sets the matrix diagonal elements from a Vec3

setZero() → void

et all elements to zero

smult(double s) → void

Matrix-scalar multiplication

solve(Vec3 b, [Vec3? target]) → Vec3

Solve Ax=b @param b The right hand side @param target Optional. Target vector to save in. @return The solution x @todo should reuse arrays

toString() → String

Returns a string representation of the matrix.

override

transpose([Mat3? target]) → Mat3

Transpose the matrix @param target Optional. Where to store the result. @return The target Mat3, or a new Mat3 if target was omitted.

vmult(Vec3 v, Vec3? target) → Vec3

Matrix-Vector multiplication @param v The vector to multiply with @param target Optional, target to save the result in.

Operators

operator ==(Object other) → bool

The equality operator.
