You must have your own marix implementations then pass the matrix data to OpenGL shaders. Furthermore, you cannot use these built-in matrix functions anymore in OpenGL programmable pipeline (GLSL) such as OpenGL v3.0+, OpenGL ES v2.0+ and WebGL v1.0+. But once your application is getting complicated, it is better to manage your own matrix implementations by yourself for all movable objects.
These built-in matrices and routines are useful to develop simple OpenGL applications and to understand the matrix transformation. OpenGL fixed pipeline provides 4 different types of matrices (GL_MODELVIEW, GL_PROJECTION, GL_TEXTURE and GL_COLOR) and transformation routines for these matrices glLoadIdentity(), glTranslatef(), glRotatef(), glScalef(), glMultMatrixf(), glFrustum() and glOrtho().
