Roundoff error can ofteh accumulate when performing computations with repeated additions and subtractions. The error accumulates differently depending on the precision with which the numbers are stored. To demonstrate this concept, consider the following summation:
The analytical result for is exactly zero, but you will find that does not equal zero when performing this computation with MATLAB due to the finite precision with which numbers are stored in memory. For this problem, write a script that performs the computation two different ways:
Use all double precision MATLABs default numbers numbers in the calculation. Assign the result for to the variable named ZeroDouble.
Use all single precision numbers in the calculation. Assign the result for using single precision to the variable named Zerosingle.
to create a single precision number, the following can be used single
Solve this problem using matlab code that uses vectors ie do not use a loop in your solution.
Hint: Declare a vector of size containing the value for each entry and then use the sum command.
