Question

Write a function myfn6 which takes as inputs vector u and value a, and output as vector

w with its elements being “True, ” or “False, ”(w = [True, False, False, …, True]). Such that

“True, ” means a is in u and “False, ” means a is not in u. Test your code for u = [0, -3, 1,

1, 2, 2, 6, 2] and a = 9, a = 1 and a = 2. Copy your code together

matlab

Answer 1

MATLAB CODE

%making the function myfn6 with arguments vector u and value a
%returns logical vector w
function w=myfn6(u,a)
%looping through the elements in u
for i=1:length(u)
    %if the element is found w at that index is made true else it is false
    if(u(i)==a)
        w(i)=true;
    else
        w(i)=false;
    end
end
%just to check if w is logical
%t=islogical(w)
end

OUTPUT

w is a logical array it can be represented in 0 and 1 only, where 0 is false and 1 is true

MATLAB CODE TO CHECK ALL ELEMENTS IN U AT THE SAME TIME

%making the function all_element_in with arguments vector u and vector a
%returns logical vector w
function w=all_element_in(u,a)
%looping through the elements in u
for i=1:length(u)
    %looping through the elements in a
    for j=1:length(a)
        %if the element is found w at that index is made true else it is false
        if(u(i)==a(j))
            w(i)=true;
            %breaking from loop
            break
        else
            w(i)=false;
    end
    end
end
%t=islogical(w)
end

OUTPUT

checks if any one element in a is in u

Please note save the code with the same name as the function
