MATLAB: Reshape matrix to have the same value every 30 cells

reshape

Hi All,

I have a question: I have a matrix

A=[10; 20; 30; 40; 50; 50; 60]

How can I reshape it in order to have a matrix (7×30) X 1 such that the first 30 values are A(1), the next 30 have value of A(2), and so on…

thanks

nikolas

This is not a reshape it's a repmat:

repmat(A, 1, 30)

Look at the diff command. It will subtract each element from the next. Look at the sign of that calculation and you will be all set.

>> A=[10; 30; 30; 40; 60; 70; 50; 50; 60; 20; 20]
A =
      10
      30
      30
      40
      60
      70
      50
      50
      60
      20
      20
>> d = diff(A)
d =
      20
       0
      10
      20
      10
     -20
       0
      10
     -40
       0
>> nnz(d > 0)
ans =
       5
>> nnz(d < 0)
ans =
       2
>> nnz(d == 0)
ans =
       3
