absolute method
Returns the component wise absolute value of this.
Implementation
Matrix2 absolute() {
final Matrix2 r = new Matrix2.zero();
final Float32List rStorage = r._m2storage;
rStorage[0] = _m2storage[0].abs();
rStorage[1] = _m2storage[1].abs();
rStorage[2] = _m2storage[2].abs();
rStorage[3] = _m2storage[3].abs();
return r;
}
