binary into matlab workspace
5 views (last 30 days)
I have a large number of bin files that I'm converting and importing the data into the matlab workspace into variable X for processing. Data is a column of numbers.
convert is a function which converts binary files in pwd directory and pulls out column i from each file and concatenates and puts into X.
What I'd like to do is
when length(X) = length(files(pwd)/2; or some value set by me
Create X1=convert(i,pwd); <-- but start i where X left off and not from begining of bin file. And so on for X2
So Id like to basically split X into X1 X2 .... which are individually small enough to fit into memory and then process them.
If I could somehow pause the execution and redirect where convert stores data without disturbing anything else.

Sorry, you are going to have to "disturb" your code interface to handle that. For example, you could have convert() output a second output that was the ftell() value of the place it left off reading, and convert() could take an second input that would be a maximum length, and a third input that would be an fseek() position to start from.
Putting the length constraint to the actual reading should not be difficult; there is an optional size parameter for fread().
