how can i do the characteristic function ?

Answer 1

[joaquinb]

My answer is based on if each element of a vector given, say "vector", is less than certain value "c". The function will return zero if the element in position j of the vector, is less than the value of "c" and one otherwise.

function z = characteristicF(vector,c)
vect = zeros(1,length(vector));
for j=2:length(vector)
        if vector(j)<c
            vect(j)=0;
        else
            vect(j)=1;
        end
end
z=vect;
end

To call this function just write the next line in the command window:

characteristicF([1,1.1,1.2,1.3,1.4,1.5],1.35)

Here, notice that your vector is

[1,1.1,1.2,1.3,1.4,1.5]

and the parameter c has value 1.35. The output is

ans =
     0     0     0     0     1     1

as you will expect. I hope it helps.

Kind sir,

I don't know what faisals question was and I assume it was homework related.

I just want to add that learning how and where to get help is an important lesson for any engineer

All the best
