MATLAB Online에서 열기 gray_image=rgb2gray(imread('image_test.jpg')); [r c]=size(gray_image); pix_prob_normal=imhist(gray_image)./(r*c); plot(0:255,pix_prob_normal); xlabel('Gray Levels'); ylabel('Pixels Probability'); ...
This MATLAB function creates a Weibull probability plot comparing the distribution of the data in x to the Weibull distribution.
Plot a histogram with Normalization set to 'pdf' to produce an estimation of the probability density function. Get x = 2*randn(5000,1) + 5; histogram(x,'Normalization','pdf') In this example, the underlying distribution for the normally distributed data is known. You can, however, use...
This MATLAB function displays a quantile-quantile plot of the quantiles of the sample data x versus the theoretical quantile values from a normal distribution.
数据的正态性检验 检查数据是否满足正态分布,一个很直观的方法是考察数据的正态概率图和QQ图。在MATLAB中可以很容易实现。 正态概率图(normal probability plot) 用于检查一组数据是否服从正态分布。是实数与正态分布数据之间函数关系的散点图。如果这组实数服从正态分布
to create a grid of points over which to evaluate the GMM. This allows you to compute the probability density function (PDF) values over a range of x and y values. After evaluating the PDF, reshape the resulting vector
