Hi everyone
I define my Variable as follow: std_msgs::Float64MultiArray Atest; I want to assign a value to specific element. for example i want to change value of fifth element to 5. how i can write it? Best
Declare the lib:
#include <std_msgs/Float64MultiArray.h> //include the lib
use it:
std_msgs::Float64MultiArray Atest; //declare Atest
Atest.data.resize(5); //resize the array to assign to existent values
Atest.data[4] = 5; //put the desired value
It works but maybe not in your case, as explained here: https://stackoverflow.com/questions/4...
Its likes a vector, dont like the array. please according to the using the way to vector, not array.
Atest.data.push_back(5.0);
it doesn't work....i've already tried it....it caused Segmentation fault (core dumped)...is it my ros problem or something else?
