Data Storage

All MATLAB data is stored columnwise, which is how Fortran stores matrices. MATLAB uses this convention because it was originally written in Fortran. For example, given the matrix

• a=['house'; 'floor'; 'porch']
  a =
     house
     floor
     porch
  

its dimensions are

• size(a)
  ans =
       3     5
  

and its data is stored as
