Question

MATLAB

Create a matrix E, using A and B vectors as row 1 and row 2 respectively

A = 10 thru 1

B = 1 thru 4.2 with ten equally spaced elements

and

1. Find the indices (row and col) within E where (prob02a, b, c, d)

   1. E = 5

   2. E > 4

   3. E < 1.9

   4. E > 1 and E < 2

Answer 1

A=10:-1:1;
B=linspace(1,4.2,10);
E=[A;B]

fprintf('E=5 indices\n')
for i=1:2
for j=1:10
if(E(i,j)==5)
fprintf('row =%d col=%d\n',i,j);
end
end
end

fprintf('\nE>4 indices\n')
for i=1:2
for j=1:10
if(E(i,j)>4)
fprintf('row =%d col=%d\n',i,j);
end
end
end

fprintf('\nE<1.9 indices\n')
for i=1:2
for j=1:10
if(E(i,j)<1.9)
fprintf('row =%d col=%d\n',i,j);
end
end
end

fprintf('\nE>1 and E<2 indices\n')
for i=1:2
for j=1:10
if(E(i,j)>1 && E(i,j)<2)
fprintf('row =%d col=%d\n',i,j);
end
end
end
