linear algebra - Error with strcmp matlab -

-

in follow-up a question of mine yesterday, tried following:

for b0, bq+1 , b did:

 bq1 = [];  (i=1:length(mte(1,:,3)))  t = sym(['bq' int2str(i)]);  bq1 = [bq1; t];  end

i ran:

>> solve(h_tot_te*b == mte(:,:,q)*bq1 + lvec + mprime*b1) error using char conversion char logical not possible.  error in solve>geteqns (line 245)   vc = char(v);  error in solve (line 141) [eqns,vars,options] = geteqns(varargin{:});

so tried:

>> solve(double(h_tot_te*b == mte(:,:,q)*bq1 + lvec + mprime*b1)) error using strcmp number of rows of string matrix must match number of elements in cell.  error in solve>geteqns (line 246)   if any(strcmp(vc, {'ignoreanalyticconstraints', 'ignorespecialcases', ...  error in solve (line 141) [eqns,vars,options] = geteqns(varargin{:});

what error mean, , how can fix it?

Android Prevent Bluetooth Pairing Dialog -

-
i'm developing internal application uses bluetooth printing. want bluetooth pairing occur without user input. have managed working trapping android.bluetooth.device.action.pairing_request broadcast. in broadcast receiver call setpin method, , pairing works ok, bluetoothpairingdialog displayed second or two, disappears - see link below. https://github.com/android/platform_packages_apps_settings/blob/master/src/com/android/settings/bluetooth/bluetoothpairingdialog.java since broadcast non-ordered, can't call abortbroadcast() , , wondering if there other way prevent pairing dialog appearing. can hook window manager in way? i haven't been able come way without modifying sdk. if you're oem, it's easy (i'm on 4.3): in packages/apps/settings/androidmanifest.xml, comment intent filter pairing dialog: <activity android:name=".bluetooth.bluetoothpairingdialog" android:label="@string/bluetooth_pairing_request"
