How to transform the contents of a matrix into integer values

[Marco Giansoldati]

Dear All,

I am working with a matrix whose content is composed by values that are codified as floating point.

I would like to kindly ask you if there is a way to transform these "values" within a matrix into integer values.

Of course I am not dealing with a variable in which case I could use the destring command.

Many thanks.

Marco

1. It it's a Mata matrix apply round() or floor() or ceil()

2. If it's a Stata matrix push into Mata ... pull out of Mata.

3. If it's a Stata matrix write your own loops over rows and columns.

4. If it's a Stata matrix use matmap (SSC).

. ssc desc matmap

TITLE
'MATMAP': module to perform elementwise calculations for matrices

DESCRIPTION/AUTHOR(S)

Given a matrix A and a user-supplied expression, matmap
calculates a matrix B in which each element is the result of
that expression given the corresponding element of matrix A. B
may overwrite A. This routine supersedes the previously posted
matewmf.
