27 | % This function parses INI file FileName and returns it as a structure with |
---|
28 | % section names and keys as fields. |
---|
29 | % |
---|
30 | % Sections from INI file are returned as fields of INI structure. |
---|
31 | % Each fiels (section of INI file) in turn is structure. |
---|
32 | % It's fields are variables from the corresponding section of the INI file. |
---|
33 | % |
---|
34 | % If INI file contains "oprhan" variables at the beginning, they will be |
---|
35 | % added as fields to INI structure. |
---|
36 | % |
---|
37 | % Lines starting with ';' and '#' are ignored (comments). |
---|

39 | % See example below for more information. |
---|
40 | % |
---|
41 | % Usually, INI files allow to put spaces and numbers in section names |
---|
42 | % without restrictions as long as section name is between '[' and ']'. |
---|
43 | % It makes people crazy to convert them to valid Matlab variables. |
---|
44 | % For this purpose Matlab provides GENVARNAME function, which does |
---|
45 | % "Construct a valid MATLAB variable name from a given candidate". |
---|
46 | % See 'help genvarname' for more information. |
---|
47 | % |
---|
48 | % The INI2STRUCT function uses the GENVARNAME to convert strange INI |
---|
49 | % file string into valid Matlab field names. |
