      Francesco Montanari authored
      * cosmo.el (cosmo-calculator): Remove age computation. It is much
        slower than other functions.
      
      * cosmo.el (cosmo-get-age): Integrate up to equality redshift.
      
      * test_cosmo.el, cosmo_compare.py: Test lookback-time and age.
      
      * README.org: Add age and lookback-time.

      Add age of the Universe · 40a88af0
      Francesco Montanari authored
      * cosmo.el (cosmo--age-integrand, cosmo-get-age, cosmo-age): Add age
        of the Universe. So far it is approximated as the age since redshift
        1000. Integrating up to larger redshifts is time consuming and most
        likely useless. However, this should be generalized (it may be
        inconsistent for exotic cosmologies).

      Fix Simpson's rule · 4b8d3549
      Francesco Montanari authored
      * cosmo.el (cosmo--trapzd, cosmo-qsimp): Check Simpson's rule for
        convergence and stop if the desired accuracy is reached. The
        previous algorithm did't perform any convergence check. At low
        redshift z~1 numerical integrals are now about one order of
        magnitude faster, at large redshift z~1 one order of magnitude
        slower (but it is guaranteed to reach the desired accuracy).
      
      * cosmo.el (cosmo, cosmo-int-prec, cosmo-int-maxsteps): Define
        customization group to allow users to set numerical integrals
        precision variable through the `customize' command.
      
      * README.org: Explain how to customize variables.

      Check convergence for Simpson's rule (commented code) · 3da5fec4
      Francesco Montanari authored
      * cosmo.el (cosmo-trapzd, cosmo-qsimp): Adapt Simpson's rule to
        automatically check convergence. At similar accuracy, the code is
        about one order of magnitude slower than the previous
        implementation. Try to improve efficiency by replacing loops with
        more functional solutions. For the time being the newly added code
        is commented out, the old implementation is used.
