Answer:
a)
inv([1 1; 100 100])
warning: matrix singular to machine precision
warning: called from ATest at line 1 column1
ans =
Inf Intf
Inf Inf
b)
A = [4, 9; 5, 11]
B = inv(A)
A*B
B*A
4. 9
5 11
-11.0000 9.0000
5.0000 4.0000
ans . 00000 -0.00000
0 . 00000 1.00000
ans 1.00000 0.00000
0.00000 1.00000
c)
x = [5; 10]
y = A*x
x = [5; 10]
y=
110 135"
d)
B * y is
5.0000
10.0000
e)
B * y
ans 5.0000
10.0000

Answer:
The program in C++ is as follows:
#include <iostream>
#include <vector>
using namespace std;
int main(){
vector<int> nums;
int num;
cin>>num;
while(num != -1){
nums.push_back(num);
cin>>num; }
for (auto i = nums.begin(); i != nums.end(); ++i){
cout << *i <<endl; }
return 0;
}
Explanation:
This declares the vector
vector<int> nums;
This declares an integer variable for each input
int num;
This gets the first input
cin>>num;
This loop is repeated until user enters -1
while(num != -1){
Saves user input into the vector
nums.push_back(num);
Get another input from the user
cin>>num; }
The following iteration print the vector elements
<em> for (auto i = nums.begin(); i != nums.end(); ++i){
</em>
<em> cout << *i <<endl; }
</em>
