MATLAB: Remove row in A by referencing on another matrix, B, with true or false to produce another matrix c

Use the same approach shown in your previous questions!

C = A(B==false,:)

MATLAB: If statement

There are two problems with your code:

"==" doesn't work well with floating point precision (EDIT: understatement)
"if (final(1,:) == final(2,:))" should read "if all(final(1,:) == final(2,:))"

--- EDIT ---

Make sure you read the link provided by Walter and Floating points by Cleve Moler. The simple rule is: never test if two floating point values are equal.

--- EDIT ---

The internal representation and what is displayed differ. With Matlab the display format can be controlled with the function, FORMAT. With format('hex') the full internal precision is shown. Try

>> v1 = 1/3;
>> v2 = 0.333;
>> v3 = 0.3333;
>> format('hex')
>> v1
v1 =
   3fd5555555555555
>> v2
v2 =
   3fd54fdf3b645a1d
>> v3
v3 =
   3fd554c985f06f69
>> 
>> format('short')
