this is my code about newff
filename = 'Book1.xlsx';
sheet = 2;
xlRange = 'D6:P16';
xlRange2 = 'P6:P17';
Data = xlsread(filename, sheet, xlRange);
data_latih = readcell(filename,'Sheet',sheet,'Range',xlRange);
target_latih = readcell(filename,'Sheet',sheet,'Range',xlRange2);
[m,n] = size(data_latih);
net = newff(minmax(data_latih),[10 1],{'logsig','purelin'},'traingdx');
but there is error
Error using minmax (line 26)
Data{1,1} is not numeric or logical.
Error in testes (line 17)
net = newff(minmax(data_latih),[10 1],{'logsig','purelin'},'traingdx');
what should I do?

You are using char type variables, i.e filename
a = {'abc', 'aa', 'b'; 'abc1', 'aa1', 'b1'}
a =
2×3 cell array
{'abc' } {'aa' } {'b' }
{'abc1'} {'aa1'} {'b1'}
>> minmax(a)
Error using minmax (line 26)
Data{1,1} is not numeric or logical.
minmax returns two columns of minimuns and maximums of numeric data
doc minmax
