Loop problem...please help

Write a MATLAB function that takes a one-dimensional array of numbers (either a

row or column vector), and removes all of the neighboring duplicated numbers. For

example, the array [1 2 2 2 3 0 1 0 0 4] becomes [1 2 3 0 1 0 4]. The function should

return the answer as a one-dimensional array of numbers in the same format as the

input. Your program should use a loop command.

Answer 1

Take a copy of the input. Go through it starting from the end. If the current entry is the same as the entry before it in the array, delete the current entry.

[Tabshir Bin Bashar]

x=[1 2 2 2 3 0 1 0 0 4];
for i=1:length(x)
    if x(i)==x(i+1)
        x(i)=[];
    end
end

tried this but not working

[Walter Roberson]

Starting from the end I said, not from the beginning . And I said to check the previous entry, not the next entr.

And watch out for your boundary condition. If you are at i = 1 then you should not be examining x(i-1)
