Hi,
I came across a representation of matrix i donot clearly understand. Is D[. , t] reprentation of a row of column vector? If not, then can anybody tell me what the dot (.) represents.
Thanks
Hey ak786.
This operation takes two matrices and augments them column-wise. To use an example from Octave:
>> >> A = [0,1,2;3,4,5;6,7,8]
A =
0 1 2
3 4 5
6 7 8
>> X = [1;2;3]
X =
1
2
3
>> B = [A, X]
B =
0 1 2 1
3 4 5 2
6 7 8 3
Note the requirement with the number of rows for each matrix.
