Class AbstractMatrixAbstract

constructor

• new AbstractMatrix(): AbstractMatrix

• Returns AbstractMatrix

_v

className

• get className(): string

• Gets the class name of this matrix instance.

  Returns string

  The name of the constructor function (class name)

isIdentityMatrixClass

• get isIdentityMatrixClass(): boolean

• Indicates whether this matrix is an identity matrix class.

  This property should be overridden in derived classes that represent identity matrices to return true.

  Returns boolean

  False for the base AbstractMatrix class

at

• at(row_i, column_i): number

• Gets the matrix element at the specified row and column.

  Parameters

  • row_i: number

    The zero-based row index
  • column_i: number

    The zero-based column index

  Returns number

  The matrix element value at the specified position

  Throws

  Error when not implemented in derived classes

determinant

• determinant(): number

• Calculates the determinant of the matrix.

  Returns number

  The determinant value of the matrix

  Throws

  Error when not implemented in derived classes

flattenAsArray

• flattenAsArray(): number[]

• Flattens the matrix into a one-dimensional array.

  Returns number[]

  A flat array containing all matrix elements in row-major order

  Throws

  Error when not implemented in derived classes

isDummy

• isDummy(): boolean

• Checks if this matrix is a dummy (uninitialized) matrix.

  A matrix is considered dummy if its internal storage has zero length, indicating it hasn't been properly initialized with matrix data.

  Returns boolean

  True if the matrix is dummy/uninitialized, false otherwise

isTheSourceSame

• isTheSourceSame(arrayBuffer): boolean

• Checks if the matrix's internal storage shares the same ArrayBuffer as the provided one.

  This method is useful for determining if two matrices share the same underlying memory, which can be important for performance optimizations and avoiding unnecessary data copying.

  Parameters

  • arrayBuffer: ArrayBuffer

    The ArrayBuffer to compare against

  Returns boolean

  True if the internal storage uses the same ArrayBuffer, false otherwise

toString

• toString(): string

• Converts the matrix to a string representation.

  Returns string

  A string representation of the matrix

  Throws

  Error when not implemented in derived classes

toStringApproximately

• toStringApproximately(): string

• Converts the matrix to an approximate string representation.

  This method is useful for displaying matrices with rounded values for better readability in debugging or logging scenarios.

  Returns string

  An approximate string representation of the matrix

  Throws

  Error when not implemented in derived classes

v

• v(i): number

• Gets the matrix element at the specified flat index.

  This provides direct access to the underlying Float32Array storage using a single index rather than row/column coordinates.

  Parameters

  • i: number

    The zero-based flat index into the matrix storage

  Returns number

  The matrix element value at the specified index
