So that should give you (assuming that you close the expression) a  
vector of values, "e" raised to a vector from elements 1441 to 1449,  
if such elements have already been defined and are numeric.

I do not think you have explained well enough. What is  
"x.reconstruida"? Does it have a longer length than myVector?

Things would be much clearer if you made a small example (not 1440  
elements long, maybe 10?).
