scorrcoef(x_pos, y_pos, x_corr, y_corr); |
Generates a spatial correlation matrix. x_pos and y_pos are vectors containing the x and y layout coordinate respectively, and x_corr and y_corr are the correlation values for the x and y coordinates respectively. Correlation is defined as a Gaussian function: $$ \begin{array}{l}{c\left[(x, y)_{i},(x, y)_{j}\right]=\exp \left(-\frac{1}{2}\left(\frac{\left(x_{j}-x_{i}\right)^{2}}{\sigma_{x}^{2}}+\frac{\left(y_{j}-y_{i}\right)^{2}}{\sigma_{y}^{2}}\right)\right)} \\ {x=\left[-\frac{x_{\text { span }}}{2},+\frac{x_{\text { span }}}{2}\right]} \\ {y=\left[-\frac{y_{\text { span }}}{2},+\frac{y_{\text { span }}}{2}\right]}\end{array} $$ |
