Example: Function Name: battleFormation formation([3 5 11, formation1.txt) Inputs: (double) 1xN vector of the number of soldiers each line 2. (char)A file name, indluding extension, for the output file group number Formation1.txt: 1 Line 1 has the following line up: e 1 1 1 0 File Outputs: 21 Line 2 has the folloOwing line up: 1 1 1 1 1 1. A text file showing the soldiers formations 3 Line 3 has the following line up: e e 1 e e Background: The date is December 21st, 1944. You are Major Hal McCown battalion commander of Notes: You are guaranteed that all numbers will be odd. There should not be an empty new line at the end of the file. the U.S. 2nd Battalion.

This is no time for poor strategy! the c ed rof each line and index from there. aboutow you The Lucky for you America has a trick up its star spangled sleeve, MATLAB! Before you charge into battle. You use MATLAB to whip p some tactical battle formations that are sure to win you the What happens when you call num 2str () on a vector of doubles? war Function Description: Write a function that that takes in the vector of soldiers in each line and outputs a file showing the soldiers' formations. To find the soldiers' formations and create the output file, follow these rules 1. Find the maximum value the input vector. Each line of the formation will have this 2, For each ine of the formation a. Put the specified number of soldiers from the input vector in the line. For example, if the first number in the vector is 3, the re are 3 soldiers in the first line. b. Align the soldiers along the center. If there are 3 soldiers and 5 spaces, there will cUse pty space at 0adh nd o or a vacant pos ition. The output file, given by the second input, should print the lines in the following format: 3. Line <num has the following line up: <formation» a. <num refers to the current line number, which should start at 1 and increment by b. Thee dlers formaton representing the positions Continued.

Answer 1

Code to copy:

%Define the function battleFormation().

function[V] = battleFormation(arr, inputFileName)

%Get the maximum value of the array arr.

maxVal = max(arr);

%Get the size of the vector arr.

[rowSize, vectorSize] = size(arr);

%Fill zeroes at odd positions.

oddArr = zeros(1, vectorSize);

%Fill zeroes in the array of vectorSize by maxVal.

reqArr = zeros(vectorSize, maxVal);

%Start a for loop till the size of the vector.

for index = 1 : vectorSize

%Get th eodd number position of the vector arr.

oddPos = mod(arr(index), 2);

%Assign this odd position value to the odd array at

%current index.

oddArr(index) = oddPos;

%End the for loop.

end

%Add the od position array values.

oddSum = sum(oddArr);

%If the sum of odd position values is not equal to the

%size of the vector.

if oddSum ~= vectorSize

%Display an error message and return from the

%function.

error('Error! Please enter odd values.');

return;

end

%Start a for loop again till the vector size.

for index = 1 : vectorSize

%Get the difference of current value from maximum

%value.

elem = maxVal - arr(index);

%Divide the required element by 2.

b = elem/2;

%Start another for loop from b + 1 to the maxVal –

%b.

for k = b + 1 : maxVal - b

%Assign 1 to the element of require array.

reqArr(index, k) = 1;

%End inner for loop.

end

%End outer for loop.

end

%Open the file name in write mode.

infile = fopen(inputFileName, 'w');

%Start another for loop till the vector size.

for index = 1 : vectorSize

%Form anther vector using reqArr.

reqVector = reqArr(index, :);

%Display the current line number with required

%formations on the file.

fprintf(infile, "\n%d| Line %d has the following line up: ", index, index);

%Start a for loop till the maxVal.

for reqIndex = 1 : maxVal

%Display the required vector.

fprintf(infile, "%d ", reqVector(reqIndex));

%End the inner for loop.

end

%End the outer for loop.

end

%Close the input file.

fclose(infile);

%Use type() command over input file.

type(inputFileName);

%Use save() command over input file name.

save(inputFileName);

%End the function.

end
