• List MDiffElementEST[matrixIN_,varno_]
  Returns the list of the different elements in the (varno). row of the specified matrixIN 
  EF – NONE
• List MPolluteEST[mx_,row_,ratio_]
  Assigns a 0 or 1 (with equal probabilities) to the randomly selected "ratio" of the elements of the matrix "mx" and returns the new "polluted" matrix.If "mx" is a List, then "row" is not relevant.
  *EF – NONE;
• List MSelectEST[MatrixIN_,varno1_,varval1_, varno2_] 
  Returns the list of "varno2" variables from the "MatrixIN" where "varno1" values equal to "varval1" 
  EF – NONE / AppendRows from LinearAlgebra`MatrixManipulation` (Optional)
• List MSwapEST[MatrixIN_,row1_,row2_] 
  Swaps the rows "row1" and "row2" in matrix "MatrixIN" 
  EF – NONE

Important!!!

Assumed form of the MatrixIN: ; (i.e., values for the same variable are stored in ROWS, NOT in COLUMNS!)

Renderu – LaTeX parsing WordPress plugin

Adapting from Titus Barik’s “LaTeX Equations and Graphics in PHP” titled article from the Linux Journal magazine, I was able to write a plugin for WordPress that enables me to include LaTeX-type

 $\sum\limits_{j = 1}^m {p\left( X \right)H\left( {Y|X = x_i } \right)} $

in the form of a PNG file format as :

(Although there is problem with multi lined entries such as matrix)

Barik’s article explained the method for Linux, but it can easily be run on a Windows environment (as it is been running on my computer at this very moment). Just install a LaTeX distribution like MikTeX and an image manipulation package like ImageMagick and it’s ready!
