>Why are you using dynamic arrays for vectors/matricies? If what you have is an actual array you wish to grow then + would likely be an append operation.
Dynamic arrays are incredibly convenient for purposes like signal processng, whe you need to handle large blocks of numeric data in variable size. What an annoyace that was in times of turbo pascal, when I had to fuff with pointers, and use procedures for simple mathametical operations. With FPC that was all gone, and I can now handle vectors the same as simple numbers. Just like matlab does: a=bxc provides the expected result regardless whether the variables are scalars, vectors or matrices. I strongly disagree with the opionon that "+" is natural to be the append operation. That may be true for strings, where it is the *only * useful operator. But for numeric vectors, *all * mathematical operators +-*/ are meaningful, and it is madness to steal one of them just for conatenation, and to obliterate all other operators for use with dynamic arrays at the same time. Obviously, if I cannot use "+", I can throw all others into the bin as well, but rather think of a different concept using procedures, like I am back in the 90s with turbo pascal. By all means, please reconsider this, and leave me the choice to define the operators. If I want "+" for concatting, it is trivial to define it myself. I don't need the language to force that and eseentially destroy operator overloading for mathematical operations on dynamic arrays. -- Sent from: http://free-pascal-general.1045716.n5.nabble.com/ _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
