# mtlb_hold

Matlab hold emulation function

## Description

There is no Scilab equivalent function for Matlab `hold` but there are equivalent instructions.

The function `mtlb_hold(flag)` is used by `mfile2sci` to replace `hold flag` when it was not possible to know what were the inputs while porting Matlab code to Scilab. This function will determine the correct semantic at run time. If you want to have a more efficient code it is possible to replace `mtlb_hold` calls:

- If `flag` is equal to "on" `mtlb_hold(flag)` may be replaced by `set(gca(),"auto_clear","off")`

- If `flag` is equal to "off" `mtlb_hold(flag)` may be replaced by `set(gca(),"auto_clear","on")`

Caution: `mtlb_hold` has not to be used for hand coded functions.
