Good morning\evening
I had an error when i reshape a matrix
when i try to reshape this matrix from (6*5) into (1*30)
C =
0 0 0 0 0 0
0 0 0 1 1 1
0 0 1 1 1 1
0 0 1 1 1 1
0 0 1 1 1 1
the result was ans =
Columns 1 through 16
0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 0
Columns 17 through 30
1 1 1 1 0 1 1 1 1 0 1 1 1 1
As you can see that the original matrix has sex zeros form the first row then followed by three zeros from the second row then three ones
But the reshaped marix has 12 zereos insted of 9 zeros
it also has other error if you see that the origenal matrix have 2 zeros in the third raw , but after reshaping it return 1 zero. The same error happen for row 4.

Hi,
the matrix is indexed columnwise. If you want to have it rowwise indexed you need to transpose:
reshape(C', 1, 30)
