Webprecision in MATLAB, which (recall) is defined as the difference between 1 and the next largest storable number. (just type eps in MATLAB to confirm). • Show your work! Start with working in binary, and show me how you get to a base-10 value for e. • Compare your value to the value eps in MATLAB. If different, explain the difference. (Hint: WebIEEE standard double precision numbers have about 16 decimal digits of accuracy, so if a matrix has a condition number of 10 10, you can expect only six digits to be accurate in the answer. If the condition number is much greater than 1/sqrt (eps), caution is advised for subsequent computations.
