Printing Vectors and Matrices:

For vector, if the conversion character and newline character are in the format string, it will print in a column in spite of of whether the vector itself is a row vector or a column vector.

>> vec = 2:5;

>> fprintf('%d\n', vec)

2

3

4

5

Note that this is a row vector. The column vector would print exactly in a similar way, as the column. Without the newline character, it would print in a row but the later prompt would appear on similar line:

>> fprintf('%d', vec)

2345>>

Though, in a script, a separate newline character could be printed to avoid such problem.

>> printvec

2345

>> 

If the number of elements in the vector is acknowledged, which many conversion characters can be specified and then the newline:

>> fprintf('%d %d %d %d\n', vec)

2 3 4 5

This is not very common, though, and is therefore not preferable.
