>Hello - Unfortunately vfp software doesn't let me create a square sparse matrix (as is doing - for example Matlab software); because I need to overcome the limit of 65,000 memory variables (even double ...) , I'm looking for a solution - anyone has a idea - it is welcome. Thanks in advance for your help, bye, Sorin


(1) Use Collections - the key would be the string of the index
For mulitdimension you'll need to add other collecttions

This becomes a bit messy

(2) If all elements are the same type, use SafeArray
SafeArrays are allocated by windows

http://msdn.microsoft.com/en-us/library/ms221145(v=VS.85).aspx

- SaveArrayCreate() or SafeArrayCreateEx() for structures
You can specify the number of dimensions and the lower/upperbounds for each dimension

- SafeArrayCreateVector() for one dimensional arrays

- SafeArrayDestroy() when you no longer need it


- SafeArrayPutElement () to assign a value to an element
- SafeArrayGetElement() to get the contents fo an element



(3) a Cursor may be the simplest way
