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

The engine that runs the computer. Small computers have one, while larger computers may
Dmitrij [34]

Answer:

CPU.

Explanation:

A processor, also known as a Central Processing Unit, is a piece of hardware in a computer that performs basic operations and control when executing program code.

Processors are usually made as integrated circuits closed in a hermetic casing, often with gold-plated leads (used for resistance to oxidation) and in this form they are called microprocessors - in common speech the terms processor and microprocessor are used interchangeably. The heart of the processor is a single crystal of silicon, on which a series of semiconductor layers have been applied by means of photolithography, forming, depending on the application, a network of several thousand to several billion transistors. Its circuits are made of metals with good electrical conductivity, such as aluminum and copper.
