Modifying values in matrix

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.

Batrisyia - this seems like homework, so please show us the code that you have written to attempt solving the question. If there is something in particular that you are having trouble with, then please post that as a question within this thread.

y = importdata('mock_Q3file.txt');

num_rows=size(y,1);

num_cols=size(y,2);

for i=1:num_rows

for j=1:num_cols

if (y(i,j)>=100 && y(i,j)<=200)

y(i,j)=100;

elseif (y(i,j)>=600 && y(i,j)<=700)

y(i,j)=600;

end

end

end

this is what i've done so far. How do i get the sum of all the values in the modified matrix?

Look this up for finding the sum

Okay thank you!
