Hi guys,
I am trying to write a module transfering from MATLAB. In order to avoid unnecessary errors, I do some input arguments checkings before processing. The user is allowed to put in only 3 arguments, that's why the last argument is a list instead of a fixed variable. Nevertheless, user has only 2 possibilities either he gives 3 or 4 inputs.
The point is I'd like to check if there is any vector in the list (last...

Incorrect vector subscript out of range
Hi all,
I'm working in visual studio 2010. I'm getting a "vector subscript out of range debug assertion check" -error, which I believe is incorrect.
I have created a minimal example:
...Code:int xsize = 4dVector.size(); int ysize = 4dVector[x].size(); int zsize = 4dVector[x][y].size(); int nbelements = 4dVector[x][y][z].size(); for (uint32_t i = 0; i < 4dVector[x][y][z].size();

im using g++ on ubuntu 10.10
i have a pointer to a vector of pointers to objects and i want to call a method on each of those objects.
oc->features is defined as:
vector<Feature* >* features;
i have to do:
...Code:vector<Feature*>::iterator it; for (it=oc->features->begin();it!=oc->features->end();it++){ Feature* a=*(it);Last edited by Niheel; Feb 9 '11, 05:08 PM. -
Python help making vectors!
Hello all,
To begin, I am working with a MySQL database using python. In the database, I am working with 3 columns: REF_ENTRY_TIME, REF_EXIT_TIME, REF_ENTRY_VALUE . My goal is to graph the net value position against time. For the time portion, both REF_ENTRY_TIME and REF_EXIT_TIME are random various times between 9:00 and 12:00. REF_ENTRY_VALUE is just a number around 100. In total I have a bout 50 columns.

C/C++ Matrix/Vector Calculation
Hey, I have a program which is done but it gives me the wrong output. It would be greatly appreciated if somebody could help me get the correct output. The question asks:
Develop a program which computes the current value of the vector {x} based on the following forward iteration: {x}(n+1) = [K] {x}(n)+ {z}, n = 0,1,2,3,4.
In other words, the next vector {x} is equal to the product of [K] and the current vector {x} + constant... -

error C2679
Hi, I'm working on a project to create a robotics simulation environment based on c++ and opengl. Right now I'm stuck trying to solve a compilation error that I'm getting while trying to push_back an object from one of my classes.
Here's part of the code:
...Code:class RobotStruct { public: RobotStruct(); virtual ~RobotStruct(); void AddJoint(float Theta, float Alpha, float a, float d, int Type); -
vector question
hello.. just started learning cpp so my question might be bit stupid.. sorry 4 that.
...Code:class Parser{ public: static vector<device*> parseConfiguration(ifstream& configFile) { string line; vector<device*> myDevices; .. ... ... if (device.compare("server") == 0) { int bufferSize; Id = helpFunctions::stoi(lineInVector[1]);
