How can I specify a tolerance for data written in two text files?

Kindly, I have data in two text files (e.g. attached) having one column each (y) and (x). I need to specify a tolorance as follows

1- combined these two text files in one.

2- get the difference between these two columns (e.g. (y^2 - x^2)^0.5 = value

3- write an output which is the maximum difference of the whole set (one value).

Sounds like homework:

1) Load the files assign it to a variable x and y.

2) Use it in the formula.

3) Use max() to find the maximum value.

4) Use dlmwrite() or any other function to export it to a text file.

Show the code that you have tried.

I tried this code but doesnot work!

 ex1 = load('x.txt');
 ey1 = load('y.txt');
 X1 = repmat(ex1(:,1), 1);
 Y1 = repmat(ey1(:,1), 1);
 TL = max(Y1.^2 - X1.^2).^0.5; 
 

[madhan ravi]

 x = load('x.txt');
 y = load('y.txt');
 Values = sqrt(y.^2 - x.^2); 
 Maximum_value=max(Values)

This is the same as mine!! I should have the absolute values in another word

-3.65 and -3.31 the difference should be 0.34

also the difference between -2.67 and -2.61 is -0.06

thank you

Use

-(y-x)% instead of sqrt(y^2-x^2)

Btw I am confused :D
