Bi-directional sigmoid, one-way sigmoid, linear function, sign function implementation on Matlab

matlab环境下，多个计算微积分和微分方程的程序(matlab environment program, multiple computing calculus and differential equations)

matlab ofdm自适应算法程序(matlab ofdm adaptive algorithm)

利用形态学方法，给ECG信号去基线漂移。基线漂移对心电影响很大。利用形态学上的腐蚀和膨胀，可以处理，但缺点是呈阶梯状，对原始信号有影响，这个是自己编的，未用matlab上的函数。(Morphological method to the ECG signal to baseline drift. Baseline drift on the ECG. Morphological erosion and dilation can handle, but the drawback is that the ladder-like effect on the original signal, this is their own series of unused matlab function.)

AC编码 好好数数够不够二十个字，嗯差不多了(AC coding)

压缩感知BP算法（basis pursuit algorithm）(basis pursuit algorithm)

This is the code for image segmentation using level set technique very good for beginning of image segmentation.

frequency response of first order discrete time systems.

将一个512×512的lena.bmp图像进行DCT变换，对得到的DCT系数按8×8块进行分层（分三层），重组填充得到新的系数矩阵，结果发现原图像的能量集中在了新图像的左上角低频部分。(The lena.bmp an image of 512 × 512 is subjected to DCT transform, the DCT coefficients obtained by layering 8 × 8 block (of three), to obtain a new recombinant filling coefficient matrix, the energy of the original image is found concentrated in upper left corner of the low-frequency part of the new image.)

MATLAB遗传算法，很详细，可以做参考(A Genetic Algorithm in MATLAB)
