fast 2D concatenation

[David Chèze]

Hello,

i'm currently using the cat(1,,) function to concatenate large arrays of
double of time series and it seems to run quite slow compared to other
operations available on arrays in scilab.
Is it a known limitation of this function and do we had better to do custom
cat function with direct initialization of the array to the max size, then
overwriting zero initialized part of the array with new read data ?

Thanks for your help,

David
