| - | * All of this is normalized (w/ Zenith Angle) | ||
| - | * X' = [X / 1 1 1 1 1 1] | ||
| - | * X'.T = [X.T | 1] | ||
| - | * X'*X'.T = [__X*X.T__ | **X1**] | ||
| - | * [1.T*X.T | m ] | ||
| - | * (X'*X'.T)/m | ||
| - | *** Mean**: X1/m | ||
| - | *__ Correlation(R)__ : X*X.T/m | ||
| - | * Samples along diagonal of correlation matrix should be similar | ||
| - | * Like toeplitz matrix | ||
