Re: [Gretl-users] Problem using printf

Using Excel data querey import did cause any problem.

I tried your script, but, could not replicate the printf-problem either. Using Excel data querey import did cause any problem. However, using "copy as csv" remains strange.

Using gretl from current git on Linux I'm not able to replicate this. Here's my test script: <hansl> matrix M = mnormal(497, 1317) scalar n1 = onenorm(M) scalar i1 = infnorm(M) outfile "matrix_test.txt" --write printf "%#24.10g", M outfile --close open matrix_test.txt --quiet matrix M2 = {dataset} scalar n2 = onenorm(M2) scalar i2 = infnorm(M2) </hansl> I create a random matrix (M) of the size you specified, write it out to a text file using "outfile" and "printf", then read it back in as a dataset, convert it back to a matrix (M2), and compare the 1- and infinity-norms of the two matrices. These values agree (and the txt file has 497 lines). This is more problematic. The results may differ by platform, and also by the application into which one attempts to paste the data. I again created a 497 x 1317 random matrix, chose "Copy as CSV" in the gretl icon view, then tried pasting into: 1) Libreoffice calc: 90 rows were imported, after which Libreoffice said "The contents of the clipboard could not be pasted". 2) Gnumeric: recognized that the clipboard data offered 497 rows, then proceeded to use 100% CPU for about 5 minutes, eventually saying "Invalid Pasting: is beyond sheet boundaries". 3) Nedit text editor: pasted 11 rows, no error message. 4) Gedit text editor: pasted all 497 rows quite quickly. When I scaled down to a 32 x 32 matrix all the above applications pasted all the data without complaint or delay. The moral here seems to be: don't try copy-and-paste on big matrices unless you're sure the target application is able to handle the incoming data. In my testing only Gedit worked correctly. All the tests above were carried out several times, and while the differences across applications seem "random", nonetheless the results appear to be deterministic: each application behaved in exactly the same way on each trial.
