am new to this matlab, my Q is probably very simple for you guys.please help me. I want to extract the random integer from the script
data = randint(1,48,2) to a new file so that the same data can be called for and use for the next iteration. someone can help me please.

If you get a little confused with fread and fwrite, then
you can try another command fprintf n fscanf
Here I give you sample code :
Let say you want to store 'data = randint(1,48,2)' into txt file.
data = randint(1,48,2)
fid = fopen('data01.txt', 'w');
fprintf(fid,'%d ',data);
fclose(fid);
And for recalling this data later, you can read from the text file you have created
fid = fopen('data01.txt');
m5 = fscanf(fid,'%d')'
fclose(fid);
Ask me again if it still difficult to understand.

You can use fwrite command to write array into binary file.
And you can use fread to read data from binary file

"count = fprintf(...) returns the number of bytes that fprintf writes."
"status = fclose(...) returns a status of 0 when the close operation is successful. Otherwise, it returns -1."
There are situations where knowing the count or status is important, but your situation is not one of them.

Hi,
when you want to use the data back in MATLAB again, the best would be a mat file, since it pretty easy:
data = randint(1,48,2)
save('filename.mat','data')
load('filename.mat')
