Question

create program using matlab, that displays number of (+) entries (=>0) in matrix and number of negative (<0). Hard code matrix in program. Use nested loops and an if-else-end structure to count (+) and (-) entries. Program should display original matrix and number of positive/negative entries.

Answer #2

**Matlab Code:**

m=input('Enter number of rows ');

n=input('Enter number of columns');

c=0; d=0;

for i=1:m

for j=1:n

a(i,j)=input('Input elements row wise-\n');

end

end

a=reshape(a,m,n);

for i=1:m

for j=1:n

if a(i,j)>0

c = c+1;

else

d = d+1;

end

end

end

fprintf('Number of +ve entries = %d\n',c)

fprintf('Number of -ve entries = %d\n',d)

**Output:**

Enter number of rows 2

Enter number of columns2

Input elements row wise-

2

Input elements row wise-

2

Input elements row wise-

3

Input elements row wise-

4

the matrix is:

a =

2 2

3 4

Number of +ve entries = 4

Number of -ve entries = 0

create program using matlab, that displays number of (+) entries
(=>0) in matrix and number of negative (<0). Hard code matrix
in program. Use nested loops and an if-else-end structure to count
(+) and (-) entries. Program should display original matrix and
number of positive/negative entries.

Create a program in C++ language, create a flowchart, provide a
screenshot of the program and output, and involve looping for your
program:
Nested loops: Challenge.
Write a program that calculates and displays the yearly amount
available if $1000 is invested in a bank account for 10 years. Your
program should display the amounts available for interest rates
from 6% to 12% inclusively, in 1% increments. Use a nested loop,
with the outer loop controlling the interest rate and the...

Q)using nested for loops to generate a 3*3 matrix where the
element value is equal to the sum of its row and column number,
except for the diagonal elements which are zeros

Using a loop (not the output format character
%o), create a program that takes a positive
integer n, and then displays the polynomial for the octal
representation of that integer. Use successive division, as
demonstrated in the binary conversion example from the lesson, to
do this. For example, for n = 157, the program should output the
following:
157 = + (5 * 8^0) + (3 * 8^1) + (2 * 8^2)
When this part is working properly, “surround” this...

Game to guess a number
%% Guess Number Game
while(1)
count=0;
guess=input('Guess a number between 0 to 10 ');
if(R>guess) disp('Your guess is too small')
elseif (R<guess)
disp('Your guess is too large')
elseif (R==guess)
disp('You are correct! It is ');guess
R=floor( rand()*10 );
end
count=count+1;
if(count==3)
break;
end
end
You need to modify this code:
(1)Player fails the game if you cannot make it within 3
tries.
(2)Player can do this game up to 10 times.
(3)If player input is...

In C# using the Console App (.NET FRAMEWORK) Create and test a
Windows Console application that displays the following patterns
separately, one after the other. You MUST use
nested for loops to generate the patterns, like the example in the
PowerPoint slides from this chapter. All asterisks (*) should be
displayed by a single statement of the form Console.Write("*");
which causes the asterisks to display side by side. A statement of
the form Console.WriteLine(); can be used to move to...

Write a code in matlab for going through every element in a
imported image matrix that has been gray scaled using for loops
(going through every row and column) and changing every element
that is equal to 255 to 1 and every number less then 255 equal to
0. Then find the x and y coordinate of each element now equal to 0
in that image matrix once again going through each row and
column.

C++ code please:
Write a program to count the number of positive and the number
of negative inputs values. The program will stop when a 0 is
input.
Ex: If the input is
-5.5 568 2.332 0
the output is
2 positive number(s) and 1 negative number(s).
Ex: If the input is
153.0 0.534 2.2 5.6 46.584 0.015 5 0
the output is
7 positive number(s) and 0 negative number(s).
