arrays - Writing a 3D Matlab matrix to a file as 1D and read it back in C -


i have three-dimensional matlab matrix, shape 3x4x5 . want write matrix .txt file 1-dimensional , read out in c.

however, numbers written should x , y dimension first (so 4x5) followed z-dimension (3).

sample code filling matrix:

duneven = 1:3*4*5 duneven = reshape(duneven,[3 4 5]);

i hoped effect permuting matrix this:

duneven = permute(duneven,[3 1 2]);

and writing out this:

fp = fopen('testuneven.txt','w'); fprintf(fp,'%f ',duneven); fclose(fp);

however, reading in c - this:

file* fp; fp = fopen("testuneven.txt","r");  for(int = 0; < 3*4*5;i++){    float var;    fscanf(fp,"%f ",&var);    printf("%f ",var); } fclose(fp);

reading out in matlab gives same output. furthermore, cat-ing out file in shell gives same results. issue located in matlab code

does not give desired output. instead prints out first cols. how can fix issue?

i guess mixed order in permute() call. inital discription of desired dimension order stats 4x5 , 3

your code

duneven = 1:3*4*5 duneven = reshape(duneven,[3 4 5]); duneven = permute(duneven,[3 1 2])

produces 5x3x4.

consider using duneven = permute(duneven,[2 3 1])

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
