How to save workspace to *.dat along with int type?

[Fangjun Jiang]

What is the format of your *.dat file? Is it a text based file?

If you have a STRUCT or CELL in the workspace, what result do you expect after saving the data to a dat file with INT type? I cannot imagine, that there is a reliable solution for the general task.

Please post any details.

>> a=[1 2 3 4]

a =

1 2 3 4

>> save a.dat a -ascii

open the a.dat, the content is as below.

1.0000000e+000 2.0000000e+000 3.0000000e+000 4.0000000e+000

It is float format.

If I wish it is integer format in a.dat.

How to use save instruction?

Thank you.

a = int32(1:4);

save a.dat a -ascii

or:

fid = fopen('a.dat', 'w');

fprintf('%d ', a);

fclose(fid);
