Unable To Download Toolbox

Im a student of manav rachna i cannot download toolbox regarding my project.
function varargout = numplate_detetion(varargin)
% NUMPLATE_DETETION MATLAB code for numplate_detetion.fig
% NUMPLATE_DETETION, by itself, creates a new NUMPLATE_DETETION or raises the existing
% singleton*.
%
% H = NUMPLATE_DETETION returns the handle to a new NUMPLATE_DETETION or the handle to
% the existing singleton*.
%
% NUMPLATE_DETETION('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in NUMPLATE_DETETION.M with the given input arguments.
%
% NUMPLATE_DETETION('Property','Value',...) creates a new NUMPLATE_DETETION or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before numplate_detetion_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to numplate_detetion_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

In this i need to download ocr based computer vision tool box
