Re: [Scilab-users] Accidentally displaying huge matrices
Hi all, What would you think about a feature describe as follows? We coud add a specific calling sequence for lines function (e.g lines(-1000)) that will switch automatically the display of Scilab to the short mode [1000x1000 constant] for a matrix (or hypermatrix) having a dimension greater that 1000.

Re: [Scilab-users] Accidentally displaying huge matrices
With the caveat that the threshold size that determines what gets displayed in its entirety and what doesn't is tunable, this works for me. The root problem that I'm addressing is the pitfall of doing something that prints for ever and ever just because I forgot the ';'.

I agree with Serge that my initial proposal using existing lines() flags and just adding a sign convention is not good, for the reason he explained, and also because such a convention would be closed, would prevent any extension for further paging or overall formating modes. But i disagree about extending format() instead, because presently format() works only on formating numbers (for disp() and string()). This would turn its role confused. I would rather advice to keep lines() to implement new paging modes -- because it is already its job, not the format()'s one : Scilab's format() is not Matlab's one --, but to extend its size. Hence, L = lines(); L(3)=100 could be a new flag thresholding full/abstract modes. In the same way, a non-wrapping mode could be tuned through L(4), instead of highjacking L(2) with any sign convention. Finally, if a compact output mode without extra blank lines should be implemented switched, lines() would also be involved, not format(). Samuel PS : format() could also be extended, in the first place for instance to replace xset(fpf,v) -- that has still no set() equivalence ; but this is another discussion. ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users

btw how can you overload the display of double matrices ? you can redefine disp(), but AFAIK it is not possible to overload the default display for native types such as booleans, decimal or complex numbers, strings...
