MATLAB: How to remove elements divisible by 3,4, and 5 in a vector

divisiblevector

I've created a vector x = 1:50 but I'm having trouble in how I can remove elements divisible by 3, 4, and 5, and then display it in a new vector. Thank you!

Best Answer

x = 1:50;
x([3:3:50,4:4:50,5:5:50]) = []

Hello,

Firstly, use the rem function to get the remainders of every value of 'i' with 3 & 5 -

r3 = rem(i,3);
r5 = rem(i,5);

Next, use if-else loops to work with different possible scenarios. Use logical operators to get desired outputs -

if ~(r3 || r5)
        disp([num2str(i),' is divisible by 3 AND 5']);
    elseif (r3 && r5)
        disp([num2str(i),' is NOT divisible by 3 or 5']);
    else
        if ~r3
            disp([num2str(i),' is divisible by 3']);
        else
            disp([num2str(i),' is divisible by 5']);
        end
    end
