matlab算法计算的源代码,希望对学matlab的同学有所帮助(algorithm matlab source code, hope to help students learn matlab)

Modulation and Demodulation of FM on MATLAB

说明：  基于matlab的子程序，可以进行任意通信信号的升余弦滤波(Subroutine based on matlab, any communication signals can be raised cosine filter)

设计一个数字滤波器，在频率低于 的范围内，低通幅度特性为常数，并且不低于0.75dB。在频率 和 之间，阻带衰减至少为20dB。 (1)试求满足这些条件的最低阶Butterworth滤波器。(Design a digital filter, in the range of frequencies below the low-pass amplitude characteristic is constant, and not less than 0.75dB. Between the frequency and stop-band attenuation of at least 20dB. (1) Determine the lowest-order Butterworth filter to meet these conditions.)

this program is for on-off-keying signalling modulation.

A Matlab object that acts just like a matrix but represents a linear operator as a function.

说明：  某城市的温度用matlab 的分析事例===数据分析的解析的结果(the temperature of a city using Matlab === examples of the analytical data analysis results)

Matlab中如何检验数据是否符合某种分布，例如:正态分布、γ分布、泊松分布、指数分布、rayleigh分布。(Matlab how to verify the data meets certain distribution, for example: the normal distribution, the γ distribution Poisson distribution, exponential distribution, rayleigh distribution.)
