Description: This MEX performs 2d bilinear interpolation using an NVIDIA graphics chipset. To compile and run this software, one needs the NVIDIA CUDA Toolkit (http://www.nvidia.com/object/cuda_get.html) and, of course, an NVIDIA graphics card of reasonably modern vintage.
BUILDING INSTRUCTIONS: Change the 'MATLAB' (and if necessary, 'MEX') variables in the Makefile to appropriate values, then simply run 'make' at a prompt and an executable (mex/mexmac/mexmaci/dll?) file will be created.
This code uses your GPU's built-in bilinear texture interpolation capability, and is very fast. For reasonably sized operations (taking, say, a 50x50 matrix up to 1000x1000) CUDA-based code is 5-10x faster than linear interp2 (as tested on a MBP 2.4GHz C2D, GeForce 8600M GT).
With very (VERY) large matrices, however, it has the capability of completely crashing your computer or giving bizarre results. Be careful!

Description: cvlib_mex is a collection (over two dozens) of matlab callable routines from the
the OpenCV library (www.intel.com/research/mrl/research/opencv/). OpenCV is a
real time computer vision library with many image processing capabilities and
it is amazingly fast as well as economic.
To get a list of all available functions run cvlib_mex without any arguments, e.g:
cvlib_mex
Dedicated (short) help on each function is obtained by runing
cvlib_mex('funname'), eg:
cvlib_mex('resize')
A longer help (but often still too short) may be obtained by consulting the
OpenCV manual pages.
To run this mex you probably need the to have all the dlls in the same directory.
Example 1: let IMG be a MxNx3 uint8 image.
imr = cvlib_mex('resize',IMG,3.4);
will resize the image, using a bilinear interpolation, to 3.4 times the original size.
Example 2: let A and B be MxN single arrays.
C = cvlib_mex('mul',A,B);
will do a per-element multiplication of A and B, or a C = A .* B
and
cvlib_mex('mul',A,B);
will do the same but in-place, storing the result in A.

Description: 基于 MATLAB 的语音信号分析与处理的课程设计.录制一段自己的语音信号，并对录制的信号进行采样；画出采样后语音信号的时域波形和频谱图；给定滤波器的性能指标，采用窗函数法或双线性变换设计滤波器，并画出滤波器的频率响应；然后用自己设计的滤波器对采集的语音信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，分析信号的变化；回放语音信号-MATLAB-based voice signal analysis and processing of the curriculum. Record a voice signal itself, and the recorded signal is sampled draw sampled speech signal time-domain waveform and frequency spectrum filter performance given by using window method or the bilinear transformation to design a filter, and draw the filter frequency response then filter of their own design collection of the speech signal is filtered, the filtered signal to draw the time domain waveform and frequency spectrum, and filter the signal before and after comparison, analysis of signal changes playback voice signal
