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: insequence.m
    path of file: ./repos/u-shape3D/software
    
    the code of the file until where you have to start completion: function [ tf ] = insequence( x, start, stop , interval)
%insequence Checks to see if value is in the sequence start:interval:stop
%
% Roughly equivalent to ismember(x,start:interval:stop)
%
% This function does not handle negative intervals
% It is faster than ismember since for a sequence one can first check to
% see if x in the interval [start stop], and then see if (x-start)/interval

%
% This function does not handle negative intervals

% INPUT
% x - vector to query if in the sequence
% start - beginning of sequence
% stop  - end
