Interface IMutableMatrix

Interface for mutable matrix operations. Extends IMatrix with methods that modify the matrix in place.

interface IMutableMatrix {
    _v: Float32Array;
    className: string;
    isIdentityMatrixClass: boolean;
    _swap(l: number, r: number): void;
    at(row_i: number, column_i: number): number;
    clone(): IMutableMatrix;
    copyComponents(mat: IMatrix): IMutableMatrix;
    determinant(): number;
    flattenAsArray(): number[];
    identity(): IMutableMatrix;
    invert(): IMutableMatrix;
    isDummy(): boolean;
    isTheSourceSame(arrayBuffer: ArrayBuffer): boolean;
    multiply(mat: IMatrix): IMutableMatrix;
    multiplyByLeft(mat: IMatrix): IMutableMatrix;
    multiplyScale(vec: IVector): IMutableMatrix;
    raw(): TypedArray;
    rotate(any: any): IMutableMatrix;
    scale(vec: IVector): IMutableMatrix;
    setAt(row_i: number, column_i: number, value: number): void;
    setComponents(...num: number[]): IMutableMatrix;
