You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: alias.m
    path of file: ./repos/chebfun/@chebtech2
    
    the code of the file until where you have to start completion: function coeffs = alias(coeffs, m)
%ALIAS   Alias Chebyshev coefficients on the 2nd kind Chebyshev grid.
%   ALIAS(C, M) aliases the Chebyshev coefficients stored in the column vector C
%   to have length M. If M > LENGTH(C), the coefficients are padded with zeros.
%   If C is a matrix of coefficients, each of the columns is aliased to length
%   M.
