I try to solve a task for my studies. We got a little framework in which we are asked to put our solution to. There is a line that I don't understand:
Mat3f R (conf.R);
Part of the task is to multiply matrices. So I guess Mat3f stands for a float matrix. But what stands the number 3 for? And what is the conf.R argument for? What will be the dimensions of the resulting matrix?
Thanks in advance!
The exact meaning of the 3 in Mat3f is library-specific, but a normal games programmer seeing it for the first time would expect Mat3f to be a 3x3 matrix.

Does Eigen contains an algorithm for solving nearest correlation matrix problems?
You can use the SelfAdjointEigenSolver to decompose your non-positive definite matrix, edit the negative eigenvalues to something slightly positive and (manually) re-compose the matrix.

I’m very new in C++ and I need your help. I want to use the input value as a mathematical function then print the result.
What i need is:
When user input: 2 +1 and hit Enter then output (cout>>)
should be your result is: 3 (the sum of 2 + 1)
The mathematical symbol could be + or * or / or -.
Could you please help me with some example?
Thanks in advance!

I am trying to use Push,Clojush,Clojure to implement an ant finding food in a 2d map, but I am not sure how to represent map? Could someone give me a example? Thank you.
You have a whole implementation of an ant simulation in Clojure at https://github.com/juliangamble/clojure-ants-simulation
To your specific question, it uses a vector of vectors:

I'm needing a elliptic filter code in c or c++, this code should filter a float input array.
Does anyone there have any code to do it?
Best
If you use e.g. MATLAB to design your filter (using e.g. the ellip function), you can take the resulting filter coefficients and very easily implement the filter in software (it's just a matter of multiplying the float values by the coefficients and following the rational filter equation).

I found implementation using 2D array http://www.geeksforgeeks.org/dynamic-programming-set-10-0-1-knapsack-problem/. But how to implement it using 1D array and if it is not possible then why?
Note that each of values in the current row uses only elements of the current and previous rows. Hence you can implement the algorithm with an array K[2][W], which is the same as using an array K[2*W] with some additional trivial index calculations
