MATLAB: Bubble sort for loop

bubble sortfor loophomework

Hi can a professional guide me in terms of a bubble sort using 2 for loops please!

I have been googling to help myself but it's challenging to understand how they actually work! I have no code!

Thanx in advance for assisting me and responding to my questions!

First try to understand the sorting algorithm. There are many videos on youtube that explains bubble sort.

Your data being x.

num = numel(x);
for j = 0 : num-1
    for i = 1: num-j-1
        if x(i)>x(i+1)
            temp = x(i);
            x(i) = x(i+1);
            x(i+1) = temp;
        end
    end
end

Not sure what is the Hankel in 4-D but by extension in 2D it should be something like this

w=5;
x=4;
y=3;
z=2;
b = rand(1,w+x+y+z);
[W,X,Y,Z] = ndgrid(1:w,1:x,1:y,1:z);
A = b(W+X+Y+Z)

MATLAB: How to plot a for loop

You’re not subscripting either ‘x’ or ‘y’. That’s important because ‘x’ is negative and zero, so it can’t be used as indices. Also, the lengths of both vectors have to be the same.

A few tweaks and your code works:

e=2.718;
x=-2:1:6;
for k1 = 1:length(x)
      if x(k1)<-1
          y(k1)=e.^(x(k1)+1);
      elseif x(k1)>=-1 && x(k1)<5
          y(k1)=2+cos(pi.*x(k1));
      elseif x>=5
          y(k1)=10.*(x(k1)-5)+1;
      else
          fprintf('\nanswer not given\n')
          y(k1) = NaN;
      end
  end
  x=-2:6;
  plot(x,y)
