Answer:

Three ways to increase the value of variable are given below. To eleborate the answer, I am taking a variable x that need to be increase.

  1. x=x+1
  2. x++
  3. x+=1

Explanation:

There are three ways to increase the value of variable.

1. x= x+1

In this case, each time value of x (variable) is incremented and stored in that variable. This equation increase the value of x by 1 each time. For Example

if x=1

then in first iteration

x= x+1 = 2;

If we want to increase the value of x by more than 1, we can add that value with x, as x+2, x+3 and so on.

2. x++

This will increment the value of x by 1. If we use this equation multiple time in program, each time it will increase 1 in value of x.

3. x+=1

This also works same as equation 1. It will increment 1 in this form and can be changed with 2, 3 and so on.

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

5. What are some situations where you might find it useful to use the “!” symbol in a program?
svlad2 [7]

Answer:

The most common use of symbols by programmers is for performing language reflection (particularly for callbacks), and most common indirectly is their use to create object linkages. In the most trivial implementation, they have essentially named integers (e.g. the enumerated type in C).
