Question
the square of the corresponding element in Q--- for example, R(1,2) will be assigned the value 49;
need help with Q#5 (vi) using Matlab
re vary from 0 to 2%, in steps of (0.01)?. Define an array ofdistances R1-5*cos(4*0) a) make a polar plot of r versus 0 with a red color linc. using the same 0 array as in (a) Q#5 Write a script which performs the following operations (in sequence) i) creates a 20 x 40 array, A, in which each element (or entry) in rows 1 through 10 is assigned the value 1 and cach element in rows 11 through 20 is assigned the () creates a new 20x40 array, B, which is the same as A except row I1 for which (iii) creates a new 20 x 41 array, C, which is the same as B for columns l through 40 (iv) creates a new 20 x 41 array, P, which is the same as C except the first ten entries ( creates a new 20 x 41 array, Q, which is the same as P except the (1.2) entry for (vi) creates a new 20 x 41 array, R, in which cach clement is the square of the value 2 B(. /j, for 1 Sjs40; but also includes a column 41 in which all elements are assigned the value 3; on the main diagonal for which P(ii)-i * c(ii), for i sis io; which Q(1,2) is assigned the value 7;
Explanation / Answer
Matlab Code
(i)
A=zeros(20,40);
A(1:10,:)=1;
A(11:20,:)=2;
disp(A);
(ii)
B=A;
j=1:40;
B(11,j)=1./j;
disp(B);
(iii)
C=zeros(20,41);
C=B;
disp(C);
(iv)
P=C;
i=1:10;
P(i,i)=i.*C(i,i);
disp(P);
(v)
Q=P;
Q(1,2)=7;
disp(Q);
(vi)
i=1:20;
j=1:41;
R=zeros(20,41);
R(i,j)=Q(i,j).*Q(i,j);
disp(R);
