Every wave is characterized by the periodic variations of any physical quantity like in sound waves a physical quantity pressure varies.A physical quantity whose periodic variations make up the matter wave, called wave function.This is a complex quantity which shows the probability of finding the particle.It is single valued, finite and continuous.With the help of wave function we can obtain the equations of motion which are as important in Quantum Physics as the Newton’s equations of motion in Classical Physics.How easily we can derive these two equations of motion which are called Time Independent and Time Dependent schrodinger equations, you can understand by these videoes.
