私はPdetoolで熱方程式を解いています。結果として、それは温度場の画像を構築する。しかし、私はその値の行列が必要です。どうすればそれを取ることができますか？MatlabのPdetoolから数値を取得する
% 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.

自動的に生成されるコードがあります。もし私がそれからtempの行列をどのように知っていれば助けてください！）
