Change matrix dimensions and keep the order

I have a 1 x 744 matrix that contains hourly data for one month. The 24 columns contain the data for one day the next 24 for the next day so on. I want to change to a matrix of 31 x 24 so that I would have the 31 days of data below each other

Use reshape. Because matlab is column-major and you want your data in row-major order, you'll reshape into 24 rows and then transpose:

result = reshape(yourmatrix, 24, []).'
