************* clear* mata beta = J(160000,1,0) mata des end ************* Why do you need to collect results in a -matrix-? I have never felt the urge to do that, which could be entirely my fault, but let`s see whether we can solve your problem more elegantly.

My simulation produces 160,000 such results but when I?m trying to create a matrix containing 160,000 rows with the following command: matrix beta = J (160000,1,0), I get the following warning : Matsize too small You have attempted to create a matrix with more than 11000 rows or columns or to fit a model with more than 11000 variables plus ancillary parameters. You need to increase matsize using the set matsize command; see help matsize. However, the ?set matsize? command doesn?t accept numbers greater than 11,000. Does anyone know if there is another command to create the matrices which doesn?t fall into the matsize limitations or any other way to circumvent this problem?
