I have a table consisting of 2500 rows and 3 columns. I recorded these vaiables at a vector having 7500 spaces. But now i want to have these values as a 2D vector. I wrote such a code:
1 2 3 4
for(i=0;i<2500;i++) {
for( int j=0;j<3;j++){
v(i)(j)=temp.at(j);
}}
but ı have an error so: term does not evaluate to a function taking 1 arguments
