Question

A vector is given by V = [4, 17,-3, 8,-7, 12, 30,-6, 6,-6,-7, 15, 4, 7, 9]. Write an m-file which doubles the elements that are positive and are divisible by 3 or 5, and, raises to the power of 4 the elements that are negative and greater than -5. If a number does not satisfy either condition, square the value. Store the modified data into a new vector Create a 2x1 subplot (stacked vertically). In the top subplot, plot the raw unaltered data as red squares. In the bottom subplot, plot the altered data as blue circles

Explanation / Answer

V = [-4, 17, -3, 8, -7, 12, 30, -6, 6, -6, -7, 15, 4, 7, 9]

X = []

for a = 1:15

   if((V(a)>=0) && (rem(V(a),3)==0 || rem(V(a),5)==0 )

        X(a) = V(a)*2

   elif(V(a)<0 && V(a)>-5)

        X(a) = V(a)^4

    else

        X(a) = V(a)*V(a)

    end

end

x = 0:0.1:10;

figure

subplot(2,1,1)      

plot(x,V, '-s','MarkerEdgeColor','red' )

title('Original Vector')

subplot(2,1,2)     

plot(x,X,'-o','MarkerEdgeColor','blue')      

title('Updated Vector')
