Construct object m:
m = memmapfile('records.dat', ...
'Offset', 2048, ...
'Format', { ...
'int16' [2 2] 'model'; ...
'uint32' [1 1] 'serialno'; ...
'single' [1 3] 'expenses'});
and display all of its properties:
disp(m)
Filename: 'd:\matlab\mfiles\records.dat'
Writable: false
Offset: 2048
Format: {'int16' [2 2] 'model'
'uint32' [1 1] 'serialno'
