Given an input array of strings (characters) s, pick out the second column of data and convert it into a column vector of data.
hodyreva [135]

Answer:

Consider the following code.

Explanation:

save the following code in read_and_interp.m

 

function X = read_and_interp(s)

[m, n] = size(s);

X = zeros(m, 1);

for i = 1:m

if(str2num(s(i, 2:5)) == 9999)

% compute value based on previous and next entries in s array

% s(i, 2:5) retrieves columns 2-5 in ith row

X(i,1) = (str2num(s(i-1 ,2:5)) + str2num(s(i+1,2:5)))/2;

else

X(i,1) = str2num(s(i,2:5));

end

end

end

======================

Now you can use teh function as shown below

s = [ 'A' '0096' ; 'B' '0114' ; 'C' '9999' ; 'D' '0105' ; 'E' '0112' ];

read_and_interp(s)

output

ans =

96.000

114.000

109.500

105.000

112.000

Consider the following declaration.int[] alpha = new int[3];Which of the following input statements correctly input values into
stepladder [879]

Answer:

Option (2) i.e., Only (ii) is the correct option to the following question.

Explanation:

Here, in the following code that is written in the Java Programming Language in which they set integer data type array variable "alpha" and set its index to 3 through "new" keyword then, we get input from the user in the index 0 then, we get input from the user in the index 1 then, again we repeat this step for index 2. So, that's why the following option is correct.

Option 1 is wrong because in this option the user input only in the index 0 and this is also the wrong way to insert value in the array variable.
