matlab - Lapack SPPTRF available? -

-

do know if matlab supports lapack spptrf function.

this function quite bargain when gotta compute cholesky factorization of huge positive definite symmetric matrix.

it allows factorization giving upper triangular matrix, stored uni-dimensional matrix, input.

or, else, chol built-in function using spptrf internally?

edit

i have been able find lapack library on file exchange http://www.mathworks.com/matlabcentral/fileexchange/16777-lapack, desired implementation of spptrf function.

edit 2

matlab running on machine fatally crashing each time call spptrf.

is there alternative way directly handle function?

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
