Logical Indexing Functionality

I'm a MathCAD 15 user. Does MathCAD have logical indexing function? In other words I want to find the indices in a matrix where the values of the matrix are within some criteria. For instance I would like to find the row and column numbers in the matrix below that are between -3.8 < G(i,j) < 2.3? Sure I could write a small function to do this but if I were using Matlab A=G(G<2.3 & G>-3.8) would get me what I need.
