1. The problem statement, all variables and given/known data The precision in MATLAB is approximately 2*10^(-16), is there a way that my computations can be calculated using a smaller precision? 2. Relevant equations 3. The attempt at a solution if i want to calculate the sum of pi^2*j where j=1:20 but i want it to be computed using high precision.if i type: b=0; for j=1:20 b=b+pi^2*j; end this would use the default double precision. I know that vpa(b) will give me (as a symbol) the answer to 32 decimal places. But, I don't want to display it in 32 deciaml places, i wan the inner computations to be calculated with a better precision (eg 32 decimal places). Any ideas will be very much appreciated.
