linear convolution in scilab
Program for linear using direct formula not using inbuilt function
//Program for Linear Convolution
clc;
clear all;
close ;
x = input('enter x seq');
h = input('enter h seq');
m = length(x);
n = length(h);
//Method : Using Direct Convolution Sum Formula
for i = 1:n+m-1
conv_sum = 0;
for j = 1:i
if (((i-j+1) <= n)&(j <= m))
