I understand that you are searching for a way to add tabulated standard deviation and variance.

The variance is calculated by taking the sum of the absolute square of each coefficient and dividing it by the total number of coefficients. The standard deviation is then obtained by taking the square root of the variance. These calculations can be used to compute the variance and standard deviation of DWT coefficients.

To know more about their usage in MATLAB, please refer to the documentation at :

Standard deviation - MATLAB std (mathworks.com)

Variance - MATLAB var (mathworks.com)
