1. The problem statement, all variables and given/known data MATLAB uses double precision as default. How can I change this to single? so that all computations will be made using single precision. 2. Relevant equations 3. The attempt at a solution I went to: file preferences virtual reality precision: floating point: single (I changed this from double to single) However, my computations are still being made in double precision. I don't want to change a single variable to single precision (this is done using single(A)) I want to change all computations. thank you.
