2． Using Gaussian elimination method and Gaussian elimination method with row scaled method to solve the following tri-diagonal system
for n=10 and 100
The algorm of viterbi. You talk to your friend three days in a row and discover that on the first day he went for a walk, on the second day he went shopping, and on the third day he cleaned his apartment. You have two questions: What is the overall probability of this sequence of observations? And what is the most likely sequence of rainy/sunny days that would explain these observations? The first question is answered by the forward algorithm the second question is answered by the Viterbi algorithm. These two algorithms are structurally so similar (in fact, they are both instances of the same abstract algorithm) that they can be implemented in a single function:
Run the SQL script given to you to create a Library database. Note that each row in the Book table denotes a book copy. Thus, if the library carries three copies of the title "DBMS", there will be three rows in the Book table, one for each copy. Write the SQL statements to do the following against the database
for entropy
H = entropy(S)
this command will evaluate the entropy of S, S should be row matrix
H = entropy([X Y Z])
this command will find the joint entropy for the 3 variables
H = entropy([X,Y],[Z,W])
this will find H(X,Y/Z,W).. you can use it for any combination of joint entropies
Please validate this function before using it
