===Purpose===


Variance scales a matrix using the log decay of the variable axis.
Version 6.7 of PLS_Toolbox and Solo was released in March, 2012.


===Synopsis===
For general product information, see [http://www.eigenvector.com/software/pls_toolbox.htm PLS_Toolbox Product Page]. For information on Solo, see [http://www.eigenvector.com/software/solo.htm Solo Product Page].


:[sx,logscl] = logdecay(x,tau)

===Description===
==NEW FEATURES==


Inputs are data to be scaled (x), and the decay rate (tau). Outputs are the variance scaled matrix (sx) and the log decay based variance scaling parameters (logscl).
===Design Of Experients (DOE) Tools===
* bla


For an m x n matrix 'x' the variance scaling used for variable 'i' is exp(-(i-1)/((n-1)\*tau)). This gives a scaling of 1 on the first variable (i.e. no scaling), and a scaling of 1/exp(-1/tau) on the last variable. The following table gives example values of tau and the scaling on the last variable:
