Dividing a vector into a matrix

I have a vector that has 40755 entries. I need to make this a multidimensional matrix where a new row is started every sixteenth entry. Any ideas? ex)

vector = [1,2,3,4,5,6,7,8,9,10,11,12]

split this up every third element

matrix [1,2,3
         4,5,6
         7,8,9,
         10,11,12]

The reshape function is your friend!

I have no idea what shape you want your result matrix to be (it’s not clear from your question), so I can’t provide specific code. (The length of your vector is not evenly divisible by (12*16), so you have to be more specific with respect to what you want reshape to produce.)
