Hi, all

In Julia, I find,if I use

`A=zeros(20,1);`

A can be a array, instead of a vector,but I want it to be a vector and I also want to use function “zeros”, How can I do it?

Thanks a lot!

The number of arguments you pass is the number of dimensions you get. So here you got a two dimensional object since you passed 20 and 1. To get a vector (a one-dimensional object), just pass one argument:

```
zeros(20)
```

Thank you very much. It seems not to be the same as MATLAB.

Maybe a quick look at this will help:
