Create a function in MATLAB which adds two discrete time signals and outputs the resultant signal. The input and output arguments of the function should be: function [y,n] = sigadd(x1,n1,x2,n2) where, x1 and x2 are amplitude values of the input discrete time signals n1 and n2 are time ranges for the input discrete time signals y is the amplitude values of the output discrete time signal n is the time range of the output discrete time signal .

where, x1 and x2 are amplitude values of the input discrete time signals
n1 and n2 are time ranges for the input discrete time signals
y is the amplitude values of the output discrete time signal
n is the time range of the output discrete time signal
