st: Mata: editing values in a matrix when a condition is met

[Pablo Mitnik <pmitnik@ssc.wisc.edu>]

Dear all,

I need to edit the values of a large matrix in Mata. More precisely, I 
need to replace all values smaller than a number X by X, and all numbers 
greater than Y by Y. The functions editvalue and _editvalue allow you to 
replace a scalar by other in a matrix, but not to specify a condition 
like x < X to trigger the replacement. Is there a way of doing this 
economically, that is, without looping over all elements of the matrix?

Any help would be greatly appreciated.

All best,

Pablo Mitnik
