Simulate standard Gaussian variates for the second series; induce correlation at lag 36. Get y2 = [randn(36,1); y1(1:end-36) + randn(T-36,1)*0.1]; Plot the XCF by using the default settings. Get crosscorr(y1,y2) All correlations in the plot are within the 2-standard-error conf...
Gaussian window, returned as a column vector. Algorithms The coefficients of a Gaussian window are computed from the following equation: w(n)=e−12(αn(L−1)/2)2=e−n2/2σ2, where –(L– 1)/2 ≤n≤ (L– 1)/2, andαis inversely proportional to the standard deviation,σ, ...
sample.state = sample.state=='sleep'; idx = find(sample.state); idxOnset = idx(1); idxWakeup = idx(end); sample.onset_gaussian = zeros(height(sample),1); sample.wakeup_gaussian = zeros(height(sample),1); y = sample{:,["onset_gaussian","wakeup_gaussian"]}; ...
下面的命令是对图像eight.tif分别加入高斯噪声、椒盐噪声和乘性噪声,其结果如图所示: 例: I=imread(‘eight.tif’); J1=imnoise(I,’gaussian’,0,0.02); J2=imnoise(I,’salt & pepper’,0.02); J3=imnoise(I,’speckle’,0.02); subplot(2,2,1),imshow(I),title(‘原图像’); subplot(2,2,2),...
峰数=3,形状=Gaussian 然后,按下F进行拟合(Fit),获得拟合结果。 拟合结果 最后,我们可以按下R键,在命令行窗口打印目标峰的具体参数。 命令行窗口打印的拟合结果 多个峰进行拟合时,我们多次按下F键后可能会得到不同的结果,这里同样建议多进行几次拟合,以找到Error最小的拟合结果。 3.常见的异常拟合问题以及问题...
This representation allows for implementing sampling strategies on top of existing functions like sampleUniform and sampleGaussian available in the StateSpace interface. To create a sample template for generating your own state sampler class, call createPlanningTemplate. The nav.StateSampler class is a ...
