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: csvd.m
    path of file: ./repos/HRTF-Individualization/model/matlabcode/functions/library/regu
    
    the code of the file until where you have to start completion: function [U,s,V] = csvd(A,tst)
%CSVD Compact singular value decomposition.
%
% s = csvd(A)
% [U,s,V] = csvd(A)
% [U,s,V] = csvd(A,'full')

% Computes the compact form of the SVD of A:
%    A = U*diag(s)*V',

% If a second argument is present, the full U and V are returned.
