I have to calculate the correlation matrix between these two variables. The matrix axes will be like variable X(first run),variable Y(first run),Variable X(second run),variable Y (second run)......I need to plot

It seems that you ask for thecorrcoef.If you look at the correlation between 2 signals you will simly get a 2-by-2 matrix which seems to be a bit small to plot as an image, but you can do something like this (for your 2 images case); ...
As a quick description, this function will create a color scale of the correlation values, and create circles in each cell of the correlation matrix/plot with the associated color. The size of the circles is also an indicator of the magnitude of the correlation, with larger circles representing...
corrMatrix = corr(data); % 计算相关矩阵 一旦我们有了相关矩阵,我们就可以使用图表视化来展示相关值的强度。我们可以使用热图来显示相关值,其中颜色的深浅表示相关值的强度。在Matlab中,我们可以使用heatmap函数来实现热图的可视化。以下是一个简单的示例代码: ...

Hcontains unique plot identifiers, which you can use to query or modify properties of the plot. Tips The settingRows="pairwise"(the default) can return a correlation matrix that is not positive definite. The settingRows="complete"returns a positive-definite matrix, but, in general, the estima...
此度量会区分预测器和响应变量。12 散点图数组使用 plotmatrix 函数比较多对十字路口之间的关系：figureplotmatrix(count)13 位于数组第 (i, j) 个位置的绘图是一个散点图，第 i 个变量位于纵轴上，第 j 个变量位于横轴上。第 i 个对角线位置的绘图是第 i 个变量的直方图。
