OptimizationVariable object

Example: var = optimvar('var',4,6)

filename — Path to file

string | character vector

Compatibility Considerations

is not recommended

Not recommended starting in R2019b

The writevar function is not recommended. Instead, use write. The write function replaces writevar and many other problem-based functions.

There are no plans to remove writevar at this time.
