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
