MATLAB rand and C++ rand() [closed]

I am trying to port a MATLAB code into C++ and found the usage of rand in MATLAB.

Is MATLAB's rand function and C++ rand() function same? If not, is there any inbuilt function for MATLAB's rand in C++ or OpenCV?

• same = is the implementation of rand in matlab and rand() in c++ same? – Pruthvi P Jun 14 '14 at 4:31

• MATLAB rand function returns uniformly distributed variable on interval $[0,1]$.
• C++ rand function returns integer between 0 and RAND_MAX, additionally it is not very 'random' function. You would also have to normalize its output. For more info please refer here: C++ rand() between 0 and 1. Although I think that you should use the uniform_int_distribution function, providing you can take the advantage of C++11 standard.
