WebAug 13, 2024 · res = s - y; end. In the above function, 'p' is a vector and 's' as well. I have to pass the vector 'p' to a c++ program to compute 's'. The above function is called several times. My idea is to first write the vector 'p' in a file, which the c++ program reads in. The c++ program writes its output 's' also in a file, which MATLAB can read in. WebRemoves from the vector either a single element (position) or a range of elements ([first,last)). This effectively reduces the container size by the number of elements removed, which are destroyed. Because vectors use an array as their underlying storage, erasing elements in positions other than the vector end causes the container to relocate all the …
