Using fprintf for matrix
235 views (last 30 days)
Show older comments
I have a matrix with 300 rows and 2 columns. For instance:
1 2
2 4
5 6
and another matrix with 300 rows and 1 column: for instance:
1
3
4
I want to convert them in the following:
-1: 1 2
-3: 2 4
-4: 5 6
It would be appreciated if you could help me. Thanks

>> X = [1,2;2,4;5,6];
>> Y = [1;3;4];
>> fprintf('-%d: %d %d\n', [Y,X].')
-1: 1 2
-3: 2 4
-4: 5 6
It is worth reading the fprintf documentation carefully, to see how it handles matrices (columnwise!) and to pick the best format string for your requirements.
