So I'm averaging a bunch of data and instead of opening up all the files manually and such, I'm using a for loop. Here's what my code looks like.
close all;
clc;
for k=1:10
filename=sprintf('20.5in_%d.bin',k);
fid=fopen('filename','r');
data=fread(fid,[1,Inf],'single');
sum=sum+data;
end
Average=sum/10;
plot(data/max(data));
plot(Average/max(Average));
close all
However, I get this error when I try to run it.
Error using fread
Invalid file identifier. Use fopen to generate a valid file identifier.
Error in in205 (line 6)
data=fread(fid,[1,Inf],'single');
I'm not sure what the problem is or how to fix it. If I don't use a loop it works so any help would be greatly appreciated!!!
close all;
clc;
fid=fopen('20.5in_1.bin','r');
data=fread(fid,[1,Inf],'single');
plot(data/max(data));
close all
^the code that works without the loop

The filename is the name held in the variable, the file isn't called 'filename'
fid=fopen(filename,'r')

Easily done. I swear sometimes the brain sees what it thinks it should be seeing, and not what is actually there
