matrix to vector matrix ?
Mostra commenti meno recenti
ok i know reshape works for this actually..but i want to reshape my matrix like this a = [111 ,101, 100]
a = [111101100]
reshape makes it like : a= [111100110]
so what i want to do is actually put all vectors behind each other..like first row then second row then third so on..is there anyway to do that ?

The solution is very simple!
MATLAB is column-major, so it works down the columns first, then the along the rows. So if you want to reshape along the rows first, you can simply transpose the input matrix before doing the reshape:
>> a = [1,1,1;1,0,1;1,0,0]
a =
1 1 1
1 0 1
1 0 0
>> reshape(a.',1,[])
ans =
1 1 1 1 0 1 1 0 0
And that's it! Just one little transpose of the input matrix makes this work. There is no need for a slow string conversion. Note that if the input array is already a character array, this method will still work:
>> a = ['111';'101';'100']
a =
111
101
100
>> reshape(a.',1,[])
ans =
111101100
