Explanation / Answer

main.m

L=input('enter elements:');

[ x ] = CreateMatrix( L );

fprintf('displaying lower triangularmatrix');

disp(x)

[ B ] = modifymatrix( x );

fprintf('displaying B');

disp(B);

CreateMatrix.m

function [ x ] = CreateMatrix( L )

S=size(L);

m=S(1);

if S(1)~=S(2)

error('matrix mast be square')

end

x=ones(1,m);

x(1,1)=b(1)./L(1,1);

%bacward substitution

for k=2:m

  

x1=1/L(k,k).*(b(k)-sum(L(k,k-1:-1:1).*x(k-1:-1:1)));

x(1,k)=x1;

end

x=x';

end

modifymatrix.m

function [ B ] = modifymatrix( x )

S=size(x);
m=S(1);
B=zeros(m,m);
for i=1:m
for j=1:m
if(x(i,j)>=0)
B(i,j)=x(i,j)*2;
end
if(x(i,j)<0)
B(i,j)=x(i,j)+5;
end
