Answer:
For n = 100
For n = 200
For n = 400
For n = 800
The faster approach is A(Bx)
Explanation step by step functions:
A(Bx) is faster because requires fewer interactions to find a result: for (AB)x you have (n*n)+n interactions while for A(Bx) you have n+n, to understand why please see the step by step:
a) Function for (AB)x:
function loopcount1 = FirstAB(A,B,x)
n = size(A)(1);
AB = zeros(n,n);
ABx = zeros(n,1);
loopcount1 = 0;
for i = 1:n
for j = 1:n
AB(i,j) = A(i,:)*B(:,j);
loopcount1 += 1;
end
end
for k = 1:n
ABx(k) = AB(k,:)*x;
loopcount1 += 1;
end
end
b) Function for A(Bx):
function loopcount2 = FirstBx(A,B,x)
n = size(A)(1);
Bx = zeros(n,1);
ABx = zeros(n,1);
loopcount2 = 0;
for i = 1:n
Bx(i) = B(i,:)*x;
loopcount2 += 1;
end
for j = 1:n
ABx(j) = A(j,:)*Bx;
loopcount2 += 1;
end
end
Answer:
<u>Explanation:</u>
An input statement using the input function at the shell prompt is as follows:
If a prompt asks for a input, a number is to be added
num = input ('Number: ')
num = num + 1
print(num)
Explanation of results: This gives error at line num= num + 1 as cannot convert int object to str implicitly
