求解这部分代码里面哪儿有错误？

clear;clc;
AnalysisDataName='S1132MA';
%加载训练的数据
oad TrainData.txt;
[TrainData_Row,TrainData_Column]=size(TrainData);
P=TrainData(:,1:TrainData_Column-1);
T=TrainData(:,TrainData_Column);
P=P';
T=T';
%对数据进行归一化处理
[AnalysisData_Assistant_Min_Max,AnalysisData_Min_Max]=WYH_Get_Min_Max(AnalysisDataName);
P=WYH_Unit(P,AnalysisData_Assistant_Min_Max);
T=WYH_Unit(T,AnalysisData_Min_Max);
