%This function plots the solution to the Schr\”{o}dinger wave equation. First, save the file in a suitable folder and change the matlab environment to that particular folder. One can call the function by giving a suitable value for the time and position, note here that the position is an array of numbers. function [ result ] = schrqd( t,x )%Name of the function. dmn = size(x);%Size of the position array. x_d = dmn(2); result = zeros(size(x));%Providing the size of ‘result’. sum_t = zeros(size(x));%Providing the size of ‘sum_t’ %For loop to recursively compute the solution.
