Correlation analysis in matlab
WebThe correlation coefficient of two random variables is a measure of their linear dependence. If each variable has N scalar observations, then the Pearson correlation coefficient is defined as ρ ( A, B) = 1 N − 1 ∑ i = 1 N ( A i − μ A σ A) ( B i − μ B σ B), WebSep 21, 2024 · When the colour distributes randomly, the data is not in correlation, like figure 1 in example.m. When two neighbouring rings share the same shape, the two properties of rings are good correlation, like figure 2 in example.m. More explanation is to be published in a paper (To be done).
