MATLAB: Matrix manipulation: split matrix in vectors

matrix arraymatrix manipulation

I have a 2447×5 matrix. I would like to split it in column vectors and than concatenate them in a single column vector (12235×1). Thanks in advance,

Mario

>> S = randi(9,3,5)
S =
     4     3     9     4     4
     6     4     2     2     9
     6     1     1     5     9
>> idx = 1==eye(size(S));
>> new = -S;
>> new(idx) = sum(new,2) + 2*S(idx)
new =
   -16    -3    -9    -4    -4
    -6   -15    -2    -2    -9
    -6    -1   -20    -5    -9

And checking:

 NewMatrix(2,2) = S(2,2)-S(2,1)-S(2,3),...S(2,n)
>> S(2,2)-S(2,1)-S(2,3)-S(2,4)-S(2,5)
ans =
   -15
>> new(2,2)
ans =
   -15

MATLAB: Matrix manipulation: update columns from stored variables

‘I have a set of variables (15) as column vectors, called A from 1-15’

If they are ‘A1’, ‘A2’, ... ‘A15’, and you only need to do this once, just type it manually:

A_Matrix = [A1 A2 A3 A4 A5 ... A15];

I will let you fill in the others.

Then save it as a ‘.mat’ file so you can simply load it when you need it.
