MATLAB: Usage Of “goto” for previous lines

equivalent for gotogotogoto alternate

hello guys Iva had a simple but confusing question… i was writing a program for Euler's formula, then I found out Matlab doesn't have any "goto" function for refering to previous lines . i was looking for an alternate and i will appreciate it if you guys help me with this 🙂 here's an example:
      x=[0.1:0.1:1]
      h=0.1
      i=1
      y(1)=1
      Z(1)=1.1
      Y(1)=1.1
      %Y'=y*(x^(1/3))
      while i<11
        y(i+1)=y(i)+(h*(x(i)*(y(i)^(1/3))))
        Z(i+1)=(x(i+1)*(y(i+1)^(1/3)))
line**  y(i+1)=y(i)+(0.5*h*(Y(i)+Z(i+1)))
        Y(i+1)=x(i+1)+y(i+1)
        if abs(Y(i+1)-Z(i+1))>0.00000000001
          Z(i+1)=Y(i+1)
          goto(line**)
        end
i=i+1
end

Best Answer

Insert this code
test=1;
while test==1
      y(i+1)=y(i)+(0.5*h*(Y(i)+Z(i+1)))
      Y(i+1)=x(i+1)+y(i+1)
      if abs(Y(i+1)-Z(i+1))>0.00000000001
          Z(i+1)=Y(i+1)
          test=1;
      else
          test=0;
      end
end
