structure

I want to calculate the mean of a list of named numbers. There are numeric(0) values that I first want to remove. Also, I would like to retrieve which elements of the list contain numeric(0) values. Here is an example how the values could look like: >r["gg",] $`01_1_er` gg 0.5176445 $`02_1_er` gg 0.4990959 $`03_1_er` gg 0.5691489 $`22_1_er` numeric(0) $`23_1_er` numeric(0) $`25_1_er` gg 0.386304 And here is the result of str: > str(r["gg",]) List of 6 $ 01_1_er: Named num 0.518 ..- attr(*, "names")= chr "gg" $ 02_1_er: Named num 0.499 ..- attr(*, "names")= chr "gg" $ 03_1_er: Named num 0.569 .

Giving the Array of Structure below: I am able to print out all values from all fields by doing: <cfset ColumnNames = structKeyArray(ApiData[1])> <cfset ColumnLength = ArrayLen(ColumnNames)> <cfloop from="1" to="#ArrayLen(ApiData)#" index="i"> <cfdump var="#ApiData[i].Created#"> <cfdump var="#ApiData[i].Name#"> ...and so on Now I am trying to loop through all fields so that I dont have to actually write the name of each field. How do I do this dynamically? Something like: <cfloop from="1" to="#ArrayLen(ApiData)#" index="i"> <cfloop from="1" to="#ColumnLength#" index="i"> <!---<cfdump var="

I dork this up just about every time I jump back into a C project. I'm getting a segfault when attempting to access a structure within a structure. Let's say I have the following (simplified) structures for a game: struct vector { float x; float y; }; struct ship { struct vector *position; }; struct game { struct ship *ship; } game; And a function to initialize the ship: static void create_ship(struct ship *ship) { ship = malloc(sizeof(struct ship)); ship->position = malloc(sizeof(struct vector)); ship->position->x = 10.0; } Then down in main(): int main() { create_ship(game.ship); printf("%f

I was asked this as interview question. Couldn't answer. Write a C program to find size of structure without using the sizeof operator. struct XYZ{ int x; float y; char z; }; int main(){ struct XYZ arr[2]; int sz = (char*)&arr[1] - (char*)&arr[0]; printf("%d",sz); return 0; } Here's another approach. It also isn't completely defined but will still work on most systems. typedef struct{ // stuff } mystruct; int main(){ mystruct x; mystruct *p = &x; int size = (char*)(p + 1) - (char*)p; printf("Size = %d\n",size); return 0; } Here's two macro versions for the two forms of sizeof (takes a type vs.

I have read many posts on this topic; among them and most recently .NET - Convert Generic Collection to Data Table . Unfortunately, all to no avail. I have a generic collection of structures : Private Structure MyStruct Dim sState as String Dim lValue as Long Dim iLayer as Integer End Structure Dim LOStates As New List(Of MyStruct) I need to fill a DataTable with this list of structures but have no idea how to go about doing this. I am using vb.net in Visual Studio 2008. Any insights will be greatly appreciated The code you linked assumes the members are declared as properties. You didn't

I have a mat-file that I accessed using from scipy import io mat = io.loadmat('example.mat') From matlab, example.mat contains the following struct >> load example.mat >> data1 data1 = LAT: [53x1 double] LON: [53x1 double] TIME: [53x1 double] units: {3x1 cell} >> data2 data2 = LAT: [100x1 double] LON: [100x1 double] TIME: [100x1 double] units: {3x1 cell} In matlab, I can access data as easy as data2.LON, etc.. It's not as trivial in python. It give me several option though like mat.clear mat.get mat.iteritems mat.keys mat.setdefault mat.viewitems mat.copy mat.has_key mat.iterkeys mat.pop mat
