我正在求解Pdetool中的熱方程。結果它建立了溫度場的圖像。但是我需要一個這些值的矩陣。我該如何接受它?在Matlab中從Pdetool獲取數字

% This script is written and read by pdetool and should NOT be edited. 
    % There are two recommended alternatives: 
    % 1) Export the required variables from pdetool and create a MATLAB script 
% to perform operations on these. 
% 2) Define the problem completely using a MATLAB script. See 
% http://www.mathworks.com/help/pde/examples/index.html for examples 
% of this approach. 
    function pdemodel 
    [pde_fig,ax]=pdeinit; 
    pdetool('appl_cb',9); 
    set(ax,'DataAspectRatio',[1 1 1]); 
    set(ax,'PlotBoxAspectRatio',[1.3333333333333333 1     6.6666666666666661]); 
    set(ax,'XLimMode','auto'); 
set(ax,'YLimMode','auto'); 
set(ax,'XTickMode','auto'); 
set(ax,'YTickMode','auto');

% Solve PDE:

有一個自動生成的代碼。如果有人知道我怎麼可以從它的溫度矩陣,請幫助!)
