Oleksandr Shepotylo ([email protected]) asked about a problem
he had compiling a function in Mata:

The compilation error Oleksandr is getting is at the line
mata matuse L:\FDI\Out\weights2rd
This is a command intended only to be used at Mata's colon prompt,
either interactively or in a do-file. It is not a Mata function
which can be compiled as part of another Mata function.
The "Remarks" section in -help mata matsave- shows the proper way using
the Mata functions fopen(), fgetmatrix(), and fclose() to read a matrix
from disk.
