read numbers from a text file & find the sum, store every result in a array in matlab

You can read numbers from a text file, calculate the sum, and store each result in an array in MATLAB using the following steps:

1. Open the text file using the fopen function and obtain the file identifier:

main.m
fileID = fopen('numbers.txt', 'r');
36 chars
2 lines

2. Read the numbers from the file using the fscanf function. Since you want to store each result in an array, you can use a loop to read the numbers until the end of the file:

main.m
numbers = [];
while ~feof(fileID)
    number = fscanf(fileID, '%f', 1);
    numbers = [numbers, number];
end
109 chars
6 lines

3. Close the file using the fclose function to free up system resources:

main.m
fclose(fileID);
16 chars
2 lines

4. Finally, calculate the sum of the numbers using the sum function:

main.m
totalSum = sum(numbers);
25 chars
2 lines

Here's the complete code snippet:

main.m
fileID = fopen('numbers.txt', 'r');
numbers = [];
while ~feof(fileID)
    number = fscanf(fileID, '%f', 1);
    numbers = [numbers, number];
end
fclose(fileID);
totalSum = sum(numbers);
186 chars
9 lines

Make sure to replace 'numbers.txt' with the path and name of your actual text file. After executing this code, the variable totalSum will store the sum of all the numbers read from the file, and the variable numbers will contain the individual numbers in an array.
