I need syntax in matlab to make the output of the for loop(Y) subtract sequentially the data (X) below and give the sum of the differences as answer. for f = [1 4 8 10 12 16 18 20]; b=2; c=1; d=1; n=4; Y=b*c*d*n*f X = [10 13 15 12 17 23 26 19]; Z = abs(Y-X); A=0; A= A+sum(Z);

Do you want this:

b=2;

c=1;

d=1;

n=4;

Y=b*c*d*n;

X = [10 13 15 12 17 23 26 19];

f = [1 4 8 10 12 16 18 20];

A=length(f)*sum(abs(Y-X));

A

Sorry I forgot to tell you that the for loop f is part of the multiplication i.e. Y = f*b*c*d*n .Please kindly correct it and re do the syntax. Thanks
