function k = speciesIndex(tp, name)

% SPECIESINDEX - The species index of species with name 'name'.
|
|
%
|
|
% The index is an integer assigned to each species in sequence as it
|
|
% is read in from the input file.
|
|
%
|
|
% If name is a single string, the return value will be a integer
|
|
% containing the corresponding index. If it is an cell array of
|
|
% strings, the output will be an array of the same shape
|
|
% containing the indices.
|
|
%
|
|
% NOTE: In keeping with the conventions used by Matlab, this method
|
|
% returns 1 for the first species, 2 for the second, etc. In
|
|
% contrast, the corresponding method speciesIndex in the Cantera C++
|
|
% and Python interfaces returns 0 for the first species, 1 for the
|
|
% second one, etc.
