Hello everyone,
I want to split a multi-column of a table into several columns and I tried to use
newtable = splitvars(tbl);
% or
newtable = splitvars(tbl, 'Multico');
But I got this error
Undefined function or variable 'splitvars'.
Could you suggest an alternative to this method?
I'm using MATLAB R2017b.
Many thanks,

Could you explain in more detail what the inputs and expected outputs would be? Maybe provide an example.

Please check the attached file.
It contains a table with 2 main columns, the first one is datetime and the second one should be splitted into 11 columns.

T = [omni(:,1), array2table(omni.Var2)];
% Specify VariableNames if you wish
% T = [omni(:,1), array2table(omni.Var2,'VariableNames',{. . .})];
Results
head(T) % show first few rows
ans =
8×12 table
omni_datetime Var1 Var2 Var3 Var4 Var5 Var6 Var7 Var8 Var9 Var10 Var11

I tried to include an AM PM in the input but still the same. Maybe it's a glitch in my matlab version. I will do it in excel.
Thank you!

The AM/PM needs to be specified in the actual time-values.
t_final = {
'00:24:05 AM'
'10:36:05 AM'
. . .
};
