Functions
add (List <double out , List <double a , List <double b → List <double
Adds two mat2's
adjoint (List <double out , List <double a → dynamic
Calculates the adjugate of a mat2
clone (List <double a → List <double
Creates a new mat2 initialized with values from an existing matrix
copy (List <double out , List <double a → List <double
Copy the values from one mat2 to another
create ()
→ List <double
2x2 Matrix
@module mat2
Creates a new identity mat2
determinant (List <double a → double
Calculates the determinant of a mat2
equals (List <double a , List <double b → bool
Returns whether or not the matrices have approximately the same elements in the same position.
exactEquals (List <double a , List <double b → bool
Returns whether or not the matrices have exactly the same elements in the same position (when compared with ===)
frob (List <double a → double
Returns Frobenius norm of a mat2
fromRotation (List <double out , double rad → dynamic
Creates a matrix from a given angle
This is equivalent to (but much faster than):
fromScaling (List <double out , List <double v → dynamic
Creates a matrix from a vector scaling
This is equivalent to (but much faster than):
fromValues (double m00 , double m01 , double m10 , double m11 → List <double
Create a new mat2 with the given values
identity (List <double out → List <double
Set a mat2 to the identity matrix
invert (List <double out , List <double a → List <double ?
Inverts a mat2
LDU (List <double L , List <double D , List <double U , List <double a → List <List <double
Returns L, D and U matrices (Lower triangular, Diagonal and Upper triangular) by factorizing the input matrix
@param {ReadonlyMat2} L the lower triangular matrix
@param {ReadonlyMat2} D the diagonal matrix
@param {ReadonlyMat2} U the upper triangular matrix
@param {ReadonlyMat2} a the input matrix to factorize
multiply (List <double out , List <double a , List <double b → List <double
Multiplies two mat2's
multiplyScalar (List <double out , List <double a , double b → List <double
Multiply each element of the matrix by a scalar.
multiplyScalarAndAdd (List <double out , List <double a , List <double b , double scale → List <double
Adds two mat2's after multiplying each element of the second operand by a scalar value.
rotate (List <double out , List <double a , double rad → List <double
Rotates a mat2 by the given angle
scale (List <double out , List <double a , List <double v → dynamic
Scales the mat2 by the dimensions in the given vec2
set (List <double out , double m00 , double m01 , double m10 , double m11 → List <double
