Table 4.

Similarity shared by the generalized correlation matrices (upper left) and the Pearson (superscript P) and the elastic network (superscript EN) correlation matrices (lower right) between the different levels of calcium

	EF–(0Ca-CaM)	EF–(2Ca-CaM)	EF–(4Ca-CaM)
EF–(4Ca-CaM)	0.45	0.49	1
EF–(2Ca-CaM)	0.68	1	0.65^P / 0.98^EN
EF–(0Ca-CaM)	1	0.73^P / 0.98^EN	0.71^P / 0.98^EN

The degree of similarity S between two matrices is evaluated as their normalized scalar product: $S = \frac{\sum_{i, j} m_{ij} n_{ij}}{\sqrt{(\sum_{i, j} m_{ij}^{2}) (\sum_{i,j} n_{ij}^{2})}}$ .
