Question

Write a function remove elt(v,a) that takes as input a vector v and a number a, and as output returns a vector that is the same as v but with a single value of a removed. For example, if we run remove elt([-2 1 3 1 5], 1 ), then the output should be either [-2 3 1 5] or [-2 1 3 5]. matlab question

Answer 1

function result = elt(v,a)
    result = [];
    k = 1;
    alreadyRemoved = false;
    for i=1:length(v)
        if(v(i)==a)
            if(alreadyRemoved==false)
                alreadyRemoved=true;
                continue;
            else
                result(k)=v(i);
                k=k+1;
            end
        else
            result(k)=v(i);
            k=k+1;
        end
    end
