Write to file inside a loop

I have this program where I open a file and write data points in it but the problem is I have to do that inside a loop. it goes:
fid=fopen('myfile2.txt','w+') % I write input to that file and pass it to my
the 4th input (input4) is being taken from a diff file.txt
more_result=[ Val M]
Then I sscanf the results to get the a specific value (M) that I want. and I want to write Val and Z in another file but I only get the last value of each in the file. because fopen(fid,'w+') keep updating inside the loop. using a+ plus doesn't help and it keeps appending and never updates after the program is done running. RIght now I am using a+ then I manually delete the content of that file after i'm done running..writing outside the loop gives me error. is there a way I can clear the file after each run? Thanks

Use 'a+' to append. You can delete() the file when appropriate, and 'a+' will create it if need be.
