Reshaping the matrix in specific order

Dear all,

Lets say I have array of multiple of 6. I want to reshape that array into matrix such as there are extactly 6 columns. Lets take example,

a = [1:18]

a = 1×18

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

b = reshape(a, [3 6])

b = 3×6

1 4 7 10 13 16 2 5 8 11 14 17 3 6 9 12 15 18

I want the output should be

1     2     3     4     5     6
7     8     9    10    11    12
13    14    15    16    17    18

Anyone can help how to do it ?

a = [1:18]

a = 1×18

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

b = reshape(a, 6, []).'

b = 3×6

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
