WebThe method returns a Matlab-style zero array initializer. It can be used to quickly form a constant array as a function parameter, part of a matrix expression, or as a matrix initializer: Mat A; A = Mat::zeros (3, 3, CV_32F ); In the example above, a new matrix is allocated only if A is not a 3x3 floating-point matrix. WebJul 30, 2024 · Here we will see what are the differences between int and const_int& in C or C++. The int is basically the type of integer type data. And const is used to make something constant. If there is int& constant, then it indicates that this will hold the reference of some int type data. This reference value is constant itself.
