I want to append array of 1xn which is having values of each iteration into mat file. eg if iteration=3 and data=1xn then i want that after iterations i will get mat file containing values like 3 rows and n columns. this mat file is inside a loop. I dont want to overwrite the values. in present code it is overwriting it.
thank you.

Note that save's -append option is very badly named: it should really be named -overwrite or something similar, because it does not "append" data to an existing variable in the .mat file, it actually completely overwrites any existing variable of the same name.

You will have to do one of these:
- on each iteration load the data, concatenate, then save the data.
- use matfile.
- collect all of the data into one array, then save it all at once after the loop.
I recommend the third option (because it is the neatest and most efficient). Use matfile for very large data sets.
