利用改进k-means算法对客户进行分类，改进rfm模型(Using improved k-means algorithm to classify customers and improve RFM model)

说明：  SQLite Table3.pas修正版，解决中文显示乱码，以及最后一字符乱码。delphi 里UTF8Encode和UTF8Decode两函数配合使用，例：获取sltb := slDb.GetTable(UTF8Encode(sSQL)); 显示字段sd.Cells[i + 1, sltb.Row + 1] :=UTF8Decode(sltb.FieldAsString(sltb.FieldIndex[sltb.Columns[i]]));(The revised version of SQLite Table 3. PAS solves the problem of Chinese display scrambling and last character scrambling. In delphi, UTF8Encode and UTF8Decode functions are used together, for example: get sltb: = slDb. GetTable (UTF8Encode (sSQL); display field sd. Cells [i + 1, sltb. Row + 1]: = UTF8Decode (sltb. Field String (sltb. Field Index [sltb. Columns [i]);)

说明：  %Fmincon Options for FMINCON % % The OPTIM.OPTIONS.FMINCON class allows the user to create a set of % options for the FMINCON solver. For a list of options that can be set, % see the documentation for FMINCON. % % OPTS = OPTIM.OPTIONS.FMINCON creates a set of options for FMINCON % with the options set to their default values. % % OPTS = OPTIM.OPTIONS.FMINCON(PARAM, VAL, ...) creates a set of options % for FMINCON with the named parameters altered with the specified % values. % % OPTS = OPTIM.OPTIONS.FMINCON(OLDOPTS, PARAM, VAL, ...) creates a copy % of OLDOPTS with the named parameters altered with the specified values. % % See also OPTIM.OPTIONS.MULTIALGORITHM, OPTIM.OPTIONS.SOLVEROPTIONS
