Parameters 

Description 

inputs [various] 

(Optional) Can be a structure generated from the LEEDR GUI followed by a comma-separated list of parameters and values to change, a comma-separated list of parameter names and parameter values to change in the current LEEDR data (or the default inputs if LEEDR data has not been generated/loaded), or the output structure resulting from a LEEDR run. If not input code will use results from LEEDR, if available.
