giving input to a code

i have 5 different matrix of same dimension.

i want to give input to my code depending upon user's choice of which matrix he wants....

can you tell me which way i should do it?

should i write matrices in five different file?

and read from file.


what would the best way to do it??

any suggestion plz.

thanks

Hi,
Use memory for storing marices only if:
1. Efficiency is a big concern
2. Your matrix is of small dimensions and you do not have too many matrices to store.

But since you have only a single matrix being read depending on the user, *files* is a better option (since the other matrices will be wasting memory )
As far as eficiency is concerned, apart from the initial overhead of loading the matrix from file to a temporary variable, there will be no difference at all.

Once you decide to use files, having the matrices in separate files is a modular, efficient, scalable and hence the best approach.


Regards,

yes...your suggestion is reasonable.....thanks
