使用matlab写得空间温度场程序，算法是高斯-塞德尔迭代法。(Room temperature using the matlab program is written, the algorithm is the Gauss- Seidel iterative method.)

完成对于图像的DCT变换反变换，FFT变换反变换，动态模糊，加噪声去噪声等等，配有图形界面，功能强大(For complete image DCT transform inverse transform, FFT transform inverse transform, as well as some dynamic blurring function, and with a graphical interface)

Statistics toolbox is necessary only to caculate t and F distributions for the number of samples at the specified alpha. These values could be obtained a table and manually inserted in the code, thus negating the use of the statistics toolbox.
