The right-hand side of the assignment in a `for`

loop can be any row vector. The left-hand side of the assignment can be any valid variable name. The `for`

loop assigns a different element of this vector to the variable each run.

```
other_row_vector = [4, 3, 5, 1, 2];
for any_name = other_row_vector
display(any_name)
end
```

The output would display

```
4
3
5
1
2
```

(The `1:n`

version is a normal case of this, because in Matlab `1:n`

is just syntax for constructing a row vector of `[1, 2, ..., n]`

.)

Hence, the two following blocks of code are identical:

```
A = [1 2 3 4 5];
for x = A
disp(x);
end
```

and

```
for x = 1:5
disp(x);
end
```

And the following are identical as well:

```
A = [1 3 5 7 9];
for x = A
disp(x);
end
```

and

```
for x = 1:2:9
disp(x);
end
```

Any row vector will do. They don't have to be numbers.

```
my_characters = 'abcde';
for my_char = my_characters
disp(my_char)
end
```

will output

```
a
b
c
d
e
```
