I have a specific question:

There is a program,which asks from the user to enter a number as an answer into a question. Later, I want this answer(a number from 3 to 10),

to be the number of rows in a table. Although I can fix simple rows,columns and name them, I cannot find a way, to develop a code

which will select the number-input of the user, as number of the rows(for example if he picks 5, I want the program to create a 5-row array)

I cannot make a pre-ordered array because I don't know what the user is going to select.

How I can ask from MATLAB to give me,as many rows, as the number that will be picked

by the user?

Here is my suggestion on how to approach this problem:

% Here is your user input
userInput = 3;
% create an array containing zeros (or uses ones if it should contain 1s)
% that has one column 
yourArray = zeros(userInput,1);
% Convert your array to a table
T = array2table(yourArray);
% Rename the column, if desired
T.Properties.VariableNames = {'NameOfColumn'};
