Produces a correlation matrix scatterplot of 2 sets of variables with least-squared fitted lines.

This function is a follow-up to the Correlation Matrix Scatterplot
(www.mathworks.com/matlabcentral/fileexchange/53043-correlation-matrix-scatterplot). It creates multiple bivariate scatterplots of 2 sets of variables. A linear fitted line, the Pearson's correlation coefficient, associated p-value, and sample size are included in each plot. It is helpful when you want to explore the relationships between 2 sets of variables.
