Write a MATLAB code that modifies the values in MockMatrix using the following conditions:
  1. A nested for loop must be used
  2. Replace values between 100 and 200 (inclusive) with 100
  3. Replace values between 600 and 700 (inclusive) with 600
Determine the sum of all the values in this new modified matrix. Use fprintf('%16.0f', total) to print all of the digits.
i've attached the data here. thank you.

Hi @Batrisyia Mohamad Asri,
To perform the required operations and get the sum of all the values in the modified matrix, you can make use of the “sum()” method.
Here is the step-by-step process:
  1. Import the file into a matrix.
y = importdata('mock_Q3file.txt');
2. Use the loops to iterate through each element and apply the replacements as required.
3. After modifying the matrix, calculate the sum of all elements using the following:
total = sum(y(:));
4. Print the results.
Please refer to the documentations for more details:
Hope this helps.
