large amounts of data. Large double-precision arrays consume a lot of memory. If the
results you want do not require that you keep the original array or intermediate arrays of data,
perform analysis operations in place where possible.
• The Interactive window maintains a record of generated code. If you forget to keep the code
from a function panel, you can cut and paste code between the Interactive and Program
windows.
Reporting Analysis Errors
The functions in the Analysis Library return status information through a return value.
If the return value
status
is zero after an Analysis Library function call, the function properly
executed with no errors. Otherwise,
status
is set to the appropriate error value. Error messages
corresponding to the possible
status
values are listed at the end of this chapter.
