Use the svd() function in matlab to compute a, the rank-1 approximation of a. clearly state what a, is, rounded to 4 decimal places. also, compute the root-mean square error (rmse) between a and a.
a=[1 2 2]
[ 3 4 5]
[ 6 7 8]
Answers
Using the knowledge in computational language in C code it is possible to write a code that organizes and calculates the value of the matrix of A*A and that is in up to 4 decimal places.
Writing the code in C is possible:
A=[1 2 2;3 4 5;6 7 8];
[u ,s ,v] = svd(A);
k = 1;
A1 = u(:,1:k)*s(1:k,1:k)*v(:,1:k)'; %'
RMSE = rms(sqrt(mean((A - A1).^2)))

Declaring a member as ____ in the base class provides access to that member in the derived classes but not to anyone else. a. public b. protected c. private d. constant
Answers
When a member is declared as b. protected in the base class, it provides access to that member in the derived classes but not to anyone else.
What is a derived class?A derived class can be defined as a type of class that inherits the information or members of a base (parent) class such as a car in a syntax.
Basically, a public class is accessible to everybody while a private class can only be accessed by users within the declared class. Also, a constant is a class whose value remains unchanged.
In Computer programming, when a member is declared as protected in the base class, it ultimately provides access to that member only in the derived classes but not to other members or anyone else.

Convert the folllowing binary number to decimal:00101
Answers
Answer:
5
Explanation:
Each digit in binary is worth double the amount compared to the number to the right of it. This means the rightmost number is 1, the second rightmost is 2, the third rightmost is 4, and so on.
If a digit has a 1 in the place, you add however much it is worth to the decimal count.
For example, this number has a 1 in the third rightmost. The third place here means a 4, so we add 4 to the count. It also has a 1 in the rightmost place, so we add 1 to the count.
Any digit with 0 is simply there to hold the place and can be ignored.

The destination transmission control protocol (TCP) process has set a 1,000-byte receive buffer window. The source TCP sequence number starts at 23,100 and sends the following segments, in order: Segment 1-200 bytes; Segment 2-300 bytes; Segment 3-200 bytes; and Segment 4-300 bytes. The last acknowledgment the source received was sequence number 23,600 saying the receive buffer can now hold 800-300 byte streams. The retransmission timer for sequence number 23,600 has expired, so what will the source TCP do next
