求助matlab程序

假设有一个矩阵[1 1 0 0;0 1 0 1;1 1 1 0;0 1 0 0],做一个程序判断如果一列中1的个数大于等于2，则t为1；若小于2，t为0.谢谢

function varargout = a1(varargin)
% A1 M-file for a1.fig
% A1, by itself, creates a new A1 or raises the existing
% singleton*.
%
% H = A1 returns the handle to a new A1 or the handle to
% the existing singleton*.
%
% A1('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in A1.M with the given input arguments.
%
% A1('Property','Value',...) creates a new A1 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before a1_OpeningFunction gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to a1_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
