When i try to do normalisation, it gives error
Error in mapminmax.create (line 12)
xmin = nnet.array.safeGather(min(x,[],2));
input data is in the below format
Date Hour DA_LMP Dry_Bulb Dew_Point System_Load
1-Jan-19 1 25.63 37 36 11,628
1-Jan-19 2 20.49 38 37 11,103
1-Jan-19 3 18.86 39 38 10,705
Code used is mentioned below:
% importing data
T=readtable('2019_SysLoad.xlsx');
input_train=T((1:5833),1:5);
target_train=T((1:5833),6);
input_test=T((5834:end),1:5);
target_test=T((5834:end),6);
[pn,ps] = mapminmax(input_train);
[tn,ts] = mapminmax(target_train);
[pn1,ps1] = mapminmax(input_test);
[tn1,ts1] = mapminmax(target_test);
kindly advice
