They both implement the Pearson correlation. However the "corr2" function implements it to 2D arrays so the internal code and functionality is different. The Pearson correlation definition used can be found in: K. Pearson, "Mathematical contributions to the theory of evolution. III. Regression,...

If all the ranks in each column are distinct, the equation simplifies to: rho(a,b)=1−6∑d2n(n2−1) , where d is the difference between the ranks of the two columns, and n is the length of each column. Tips The difference between corr(X,Y) and the MATLAB® function cor...

The corr function returns model-implied temporal correlations and covariances of the state or measurement variables in a stationary, time-invariant state-space model. To determine whether the model captures characteristics present in the data, You can compare model-implied associations of present and ...
This MATLAB function returns the sample autocorrelation function (ACF) and associated lags of the input univariate time series.

This MATLAB function computes the rigid transformation that registers the moving point cloud moving, to the fixed point cloud fixed, using an image-based phase correlation algorithm.
线性相关是讨论两信号之间的同步性（synchronism ）或相似性(similarity)或同相性(in-phase)或两信号的变化规律是否具有线性关系(linear relationship)或接近线性关系的程度。这里还要给出相关函数(correlation Function)（在医学统计里一般是不给出的）和相关系数（correlation coefficient ）这两个相联系而又不同的概念。...
A common research task in dendroclimatology is identification of the monthly or seasonal climate signal in an annual time series of indices of ring width. A MATLAB function, seascorr, is introduced as a general statistical tool for identifying the signal. Monthly time series of primary and ...
