Bases: Command

Gendaymtx command.

Gendaymtx takes a weather tape as input and produces a matrix of sky patch values using the Perez all weather model. The weather tape is assumed to be in the simple ASCII format understood by DAYSIM, which contains a short header with the site parameters followed by the month, day, standard time, direct normal and diffuse horizontal irradiance values, one time step per line. Each time step line is used to compute a column in the output matrix, where rows correspond to sky patch positions, starting with 0 for the ground and continuing to 145 for the zenith using the default -m 1 parameter setting.

Parameters:

  • options – Gendaymtx options. It will be set to Radiance default values if unspecified.

  • output – Path to output file.

  • wea – Path to input wea file.
