Make an awesome ramp for a tiny motorcycle stuntman | MATLAB CODY Problem

Given a vector, say v=[1 3 6 9 11], turn it into a matrix 'ramp' like so:

m=[1 3 6 9 11;
   3 6 9 11 0;
   6 9 11 0 0;
   9 11 0 0 0;
   11 0 0 0 0]

That way a tiny motorcycle stuntman can follow the trace and jump over 9 school buses safely.

MATLAB CODE:

Main Body:

clc

clear all

close all

x=input('Enter the array:');

r=length(x);

z=[];

z=[z x'];

for i=1:length(x)-1

    x=ci(x);

    z=[z x'];

end

 Function:

function y=ci(x)

z=length(x);

y=[];

for i=2:length(x)

    y=[y x(i)];

end

c=length(y);

for i=length(y)+1:z

    y=[y 0];

end

end
