环境：python 3.5

matlab R2016b    注意：matlab2016 支持的python最高版本为3.5

步骤1: 进入此文件夹 运行命令：

python setup.py install

pip 安装各种包

步骤三： 你就可以使用呢

接下里验张python 和MATLAB 混编,本文作者采用的是python 调用matlab ,

MATLAB代码：

function  a = triangle(b,h)
    Fs = 1000;            % Sampling frequency
    T = 1/Fs;             % Sampling period
    L = 1000;             % Length of signal
    t = (0:L-1)*T;        % Time vector
    S = 0.7*sin(2*pi*50*t) + sin(2*pi*120*t);
    %Corrupt the signal with zero-mean white noise with a variance of 4.
    X = S + 2*randn(size(t));
    figure();
    subplot(211);
    plot(1000*t(1:50),X(1:50))
    title('Signal Corrupted with Zero-Mean Random Noise')
    xlabel('t (milliseconds)')
    ylabel('X(t)')
    Y = fft(X);
    P2 = abs(Y/L);
    P1 = P2(1:L/2+1);
    P1(2:end-1) = 2*P1(2:end-1);
    f = Fs*(0:(L/2))/L;
    subplot(212)
    plot(f,P1)
    title('Single-Sided Amplitude Spectrum of X(t)')
    xlabel('f (Hz)')
    ylabel('|P1(f)|')
    a=1

python 代码：

# coding=utf-8
    import time
    import matlab.engine
    import os
    eng = matlab.engine.start_matlab()
    fs=360
    print(eng.triangle(2,3))
    os.system("pause")
    #time.sleep(10)
    #[RR,brady,tachy,PVC,PAC]=eng.ECG_diagnosis(sig,fs)
    #print (ans)
    eng.quit()
