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.
