Systems of two ordinary and partial differential equations (ODEs and PDEs)had been obtained from a scalar complex ODE by splitting it into its real andimaginary parts. The procedure was also carried out to obtain a fourdimensional system by splitting a complex system of two ODEs into its real andimaginary parts. Systems of three ODEs had not been accessible by thesemethods. In this paper the complex splitting is used iteratively to obtainthree and four dimensional systems of ODEs and four dimensional systems of PDEsfor four functions of two and four variables. The new systems of four ODEs aredistinct from the class obtained by the single split of a two dimensionalsystem. Illustrative examples are provided.
