matlab - Memory issue with UIGETDIR -


recently, have noticed odd behavior uigetdir function of matlab.

if have string values, has no effect on memory.

>> memory maximum possible array:    860 mb (9.014e+08 bytes) memory available arrays:   1287 mb (1.349e+09 bytes) memory used matlab:    435 mb (4.557e+08 bytes) physical memory (ram):   3317 mb (3.478e+09 bytes)  >> folder = 'c:\users\mrawesome';  >> memory maximum possible array:    860 mb (9.014e+08 bytes) * memory available arrays:   1289 mb (1.352e+09 bytes) ** memory used matlab:    434 mb (4.553e+08 bytes) physical memory (ram):   3317 mb (3.478e+09 bytes)

but if use uigetdir instead, drains down whole lot of memory:

>> folder2 = uigetdir;  >> memory maximum possible array:    727 mb (7.628e+08 bytes) * memory available arrays:   1153 mb (1.208e+09 bytes) ** memory used matlab:    458 mb (4.806e+08 bytes) physical memory (ram):   3317 mb (3.478e+09 bytes)

and if clear these 2 variables memory, not release memory!

i looked up, , found nothing on issue anywhere.

first, know how use (or what use instead of) uigetdir effectively?
second, know how free memory functions/variables this?
