plotmatrixcorr

Easy way to generate a scatter plot including a linear fit.

PLOTMATRIXCORR The function takes each column of a matrix as a variable
and create the scatter plot of the correlation between variables.
The function sets a linear model to the data and graph the results in
the upper diagonal matrix. In the main diagonal places the name of the
variable and the lower triangular matrix shows the linear fit equation,
the coefficient of determination and Pearson correlation.

PLOTMATRIXCORR(X) scatter plots the columns of X where each column
represents a variable
PLOTMATRIXCORR(X,LABELS) put the labels of LABELS input into the main
diagonal (P1, P2, P3,..., Pn as default)
Example

r=rand(5);
plotmatrixcorr(r)
