Question

Don't really know where to begin but here's what information theygive and what i have so far. I guess what my question is, is whatam i suppose to do and how am i suppose to do it. It says i need touse iteration, so that means "for x=" then if->else if>elseif->else-> end" format right? SO could someone help me startit

Separating a vector into 6 subsets:

http://img23.imageshack.us/img23/2995/44567558.png
%Use the following vector given for Matlab:
D = [ 23, -5, 4, 0, -10, 45, 3, -3, 34, -9, 1, 25, 87, 21,-7, 4, -2, 6, 62, -22, -6, -17]

posEven = [4,34,4,6,62]

negEven = [-10,-2,-22,-6]

posodd = [23,45,25,87,21]

negodd = [-5,-3,-9,-7,-17]

posNeg = [1, 0, 1, 0, 0, 1, 1, 0, 1, 0, 1, 1, 1, 1, 0, 1, 0, 1, 1,0, 0, 0]

big = [45, 34, 87, 62]





Example given to us:

If D = [-4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 34, 87],
posEven=[2,4,34]
negEven=[-4,-2]
posOdd=[l,3,5,87]
negodd=[-3,-1]
posNeg = [0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 1] and
big = [34, 87]

Use the following vector (copy and paste in Matlab):

D = [ 23, -5, 4, 0, -10, 45, 3, -3, 34, -9, 1, 25, 87, 21,-7, 4, -2, 6, 62, -22, -6, -17]

Explanation / Answer

He, I have created your program. 1) Determine if the number is positive or negative 2) determine if the number is odd or even For this, mod(number,2) is used. 3) Add the numbers to vectors If it is unclear, send a private message! D = [ 23, -5, 4, 0, -10, 45, 3, -3, 34, -9, 1, 25, 87, 21,-7, 4, -2, 6, 62, -22, -6, -17]; %%%%%%%%%%%%%%%%% Initialize Parameters%%%%%%%%%%%%% SumPosEven = 0; SumPosOdd = 0; PosEven    = []; PosOdd     = []; SumNegEven = 0; SumNegOdd = 0 ; NegEven    = []; NegOdd     = []; Big        = []; SumBig     = 0; PosNeg     = []; SumPosNeg = 0; %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% for i=1:length(D)     % Negativenumbers     if D(i) < 0       SumPosNeg = SumPosNeg +1;       PosNeg(SumPosNeg)=0;                    % determine if a number is odd oreven       % modlus(number,2)= 0 for evennumbers       ifmod(D(i),2)== 0           SumNegEven =SumNegEven +1;          NegEven(SumNegEven)=D(i);       end       ifmod(D(i),2) == 1           SumNegOdd =SumNegOdd +1;          NegOdd(SumNegOdd)= D(i);       end          end     % PositiveNumbers     if D(i) > 0       SumPosNeg = SumPosNeg +1;       PosNeg(SumPosNeg)=1;                     ifmod(D(i),2)== 0           SumPosEven =SumPosEven +1;          PosEven(SumPosEven)=D(i);       end       if mod(D(i),2) == 1           SumPosOdd =SumPosOdd +1;          PosOdd(SumPosOdd)= D(i);        end       if D(i)>25           SumBig =SumBig +1;          Big(SumBig)=D(i);       end     end        end;    % Results PosEven PosOdd NegEven NegOdd Big PosNeg
