Question
need help with Q#5 (4) using Matlab
ev arv from10 to 2t in steps of (0.01)r. Define an array of distances r RI=5*cos(4*0) al make a polar plot of r versus 0 with a red color line. using the same 0 array as in (a) Write a script which performs the following operations (in sequence) (i) Q#5 creates a 20 x 40 array, A, in which each element (or entry) in rows l through 10 is assigned the value 1 and each element in rows 11 through 20 is assigned the value 2; creates a new 20x40 array, B, which is the same as A except row I1 for which B( 1 I j) = 1/j, for 1 js 40; (ii) (ii) (iv) creates a new 20 x 41 array, C, which is the same as B for columns 1 through 40 but also includes a column 41 in which all clements are assigned the value 3; creates a new 20x 41 array, P, which is the same as C except the first ten entries on the main diagonal for which PG,i)-i * C(i,i), for l s is 10:Explanation / Answer
