Prevent clearing function from memory
mlock
mlock locks the currently
running function in memory so that subsequent clear functions
do not remove it. Locking a function in memory also prevents any persistent variables defined in the file
from getting reinitialized.
Use the munlock function
to return the file to its normal, clearable state.
The function testfun begins with an mlock statement.
function testfun mlock . .
When you execute this function, it becomes locked in memory.
You can check this using the mislocked function.
testfun
mislocked('testfun')
ans =
1Using munlock, you unlock the testfun function
in memory. Checking its status with mislocked shows
that it is indeed unlocked at this point.
munlock('testfun')
mislocked('testfun')
ans =
