how to get Pearson coefficient in the single vector not in the matrix

Hi,

is there any possible where i can get pearson cofficient in the single vector? i have tried with the [R,P] = corrcoef(___) but it gives in matrix form

please help

Hi,

Pearson coefficient measures the strength and direction of a linear relationship between two variables.

For example :

x = randn(6,1);
y = randn(6,1);
A = [x y 2*y+3];
R = corrcoef(A)

R = 3×3

1.0000 -0.7991 -0.7991 -0.7991 1.0000 1.0000 -0.7991 1.0000 1.0000

As you can see that there is a linear relation between second and third element of the A, this is information is given by "corrcoef" function.

Thus, it is not possible to capture this relation in a single vector.
