示例1:
outMat2d = mat2d.fromRotation(outMat2d, 0.5);
outMat2d = mat2d.fromScaling(outMat2d, vec2A);
outMat2d = mat2d.fromTranslation(outMat2d, vec2A);
outStr = mat2d.str(mat2dA);
outVal = mat2d.frob(mat2dA);
outMat2d = mat2d.add(outMat2d, mat2dA, mat2dB);
outMat2d = mat2d.subtract(outMat2d, mat2dA, mat2dB);
outMat2d = mat2d.sub(outMat2d, mat2dA, mat2dB);
outMat2d = mat2d.multiplyScalar (outMat2d, mat2dA, 2);
outMat2d = mat2d.multiplyScalarAndAdd (outMat2d, mat2dA, mat2dB, 2);
outBool = mat2d.exactEquals(mat2dA, mat2dB);
outBool = mat2d.equals(mat2dA, mat2dB);
// mat3
outMat3 = mat3.create();
outMat3 = mat3.fromMat4(outMat3, mat4A);
outMat3 = mat3.clone(mat3A);
