hello all,
I want to dispaly the threshold and u2 to the Switch Block in smulink, but I don't know how to set it.

See my demo (simply copy and paste):
clc; % Clear the command window.
close all; % Close all figures (except those of imtool.)
imtool close all; % Close all imtool figures.
clear; % Erase all existing variables.
workspace; % Make sure the workspace panel is showing.
fontSize = 20;% Change the current folder to the folder of this m-file.
if(~isdeployed) cd(fileparts(which(mfilename)));end % Check that user has the Image Processing Toolbox installed.
hasIPT = license('test', 'image_toolbox');if ~hasIPT % User does not have the toolbox installed.
message = sprintf('Sorry, but you do not seem to have the Image Processing Toolbox.\nDo you want to try to continue anyway?'); reply = questdlg(message, 'Toolbox missing', 'Yes', 'No', 'Yes'); if strcmpi(reply, 'No') % User said No, so exit.
return; endend% Read in a standard MATLAB gray scale demo image.
folder = fullfile(matlabroot, '\toolbox\images\imdemos');baseFileName = 'cell.tif';fullFileName = fullfile(folder, baseFileName);% Get the full filename, with path prepended.
fullFileName = fullfile(folder, baseFileName);if ~exist(fullFileName, 'file') % Didn't find it there. Check the search path for it.
fullFileName = baseFileName; % No path this time.
if ~exist(fullFileName, 'file') % Still didn't find it. Alert user.

[rows columns numberOfColorBands] = size(grayImage);% Display the original gray scale image.
subplot(2, 2, 1);imshow(grayImage, []);title('Original Grayscale Image', 'FontSize', fontSize);% Enlarge figure to full screen.
set(gcf, 'Position', get(0,'Screensize')); set(gcf,'name','Demo by ImageAnalyst','numbertitle','off') % Threshold the image.
binaryImage = grayImage >= 70 & grayImage <= 130;% Display the binary image.
subplot(2, 2, 2);imshow(binaryImage, []);title('Binary Image', 'FontSize', fontSize);% Mask the image.
maskedImage = grayImage; % Initialize.
maskedImage(~binaryImage) = 0;% Display the masked image.
subplot(2, 2, 3);imshow(maskedImage, []);title('Masked Image', 'FontSize', fontSize);msgbox('Done with demo!');パラメータ推定に必要なものは、入出力データです。推定したいパラメータは、変数で定義し、ベースワークスペースで初期値を設定します。入力データが入る箇所にInportブロックを、出力データに対応する箇所に Outportブロックを配置します。パラメータ推定GUIを起動し、入出力データと推定するパラメータを定義し、推定を行います。 下記URLで紹介されているデモが、もっともシンプルでわかりやすいかと思いますので、こちらで手順を確認することをお勧めします。
