i have a matrix with have all sorts of values, like 1.062e+03 or 7.5646546.
i want to change the variable storage format to nonexponential and to 2 digits after decimal, for example 1062 and 7.56, because later on i'm displaying it in a uitable.
thank you

"i want to change the variable storage format to nonexponential and to 2 digits after decimal, for example 1062 and 7.56"
This makes no sense. How numbers are stored in memory is totally irrelevant to how they are displayed in something like a uitable. If both of those numbers are class double then there is absolutely no distinction between how the values 1.062e+03 or 7.5646546 are stored in memory, and absolutely no way to change that storage (short of changing the value or storing it using a different class).
Do NOT confuse how numbers are stored in memory (esp. the class) with how a number is displayed (controlled by format, fprintf, the Variable Viewer, etc).

"just to change the storage format"
You can't. Numeric classes do NOT store any information on how values are displayed.
