Do you want to assign names for a table object inside Matlab or to modify the file?

Hope you have already imported data into workspace as table. Assuming table name is Reducedfeatures
% for defining name for all columns at once
Reducedfeatures.Properties.VariableNames = {'C1','C2',.......}
% for defining specific column names, example: first and second column
Reducedfeatures.Properties.VariableNames([1:2]) = {'C1','C2'}

To create the list of names dynamically:
Reducedfeatures.Properties.VariableNames = sprintfc('Hist_fea%d', 1:23)

Hello
I'm following your example but I'm getting this message
Unable to perform assignment
because dot indexing is not
supported for variables of this
type.

@Claudio: Please post your code. How is your variable called "Reducedfeatures" here defined in your case?
