Error using load Can't read file

Hi guys, I want to load a mat. file, sometime it works, and sometime it doesnot work,saying'Error using load Can't read file'. When i use the 'exist()', it returns 2. Sometime i need to restart my MATLAB, then the data can be loaded successfully. Please help me to figure this out. Thank you very much!

I had a similar problem (opening a 1GB mat-file that DID exist in the current folder). After a simple "clear all", I could load the file.

It's always due to running out of memory. I close other programs and restart MATLAB then it works.

Hello, I have the same problem as Zhentong, and it is not due to "No such file or directory", the file definitely exists.

It is fine to load small .mat file, but when I try to load ones that's several hundreds of MB, it will not succeed until i restart the MATLAB which is an annoying issue.

Really appreciate any insight on this!

[Joseph Cheng]

is this file on a network drive?

[shelley]

no, it is local.

Is the file open already?

Did you exhaust the number of files open at the same time?

What does this reply:

fopen('all');

[shelley]

no, the file is not opened, it replies ans =

     []

Hi All I just learned that this problem could likely be due to "fragmentation" issue associated with Windows XP 32-bit system. Refer to this link on " Long-Term Usage (Windows Systems Only) "

Answer 5

[Xikang Luo]

yeah, I agree with that； It's always due to running out of memory. I close other programs and restart MATLAB then it works.

I try clear some other matrix and it worked!

I have R2019b, still encountering loading problem as below. I tried 'clear all', closing all other programs and restart MATLAB. My Java Heap Memory is maxed out (2,018 MB). OS is 64-bit, Windows 10. The specific file that I'm trying to load is a very big structure containing 3 fields.

>> load('Channel_1_tracking_result.mat','tracksFinal')
Error using load
Unable to read MAT-file
Not a binary MAT-file. Try load -ASCII to read as text.

[erencaglar]

did you solve the problem?

[Tra Ngo]

Not really. I resorted to using a 32GB Ram CPU, instead of the 8GB Ram one I was using to load the file. Somehow, when I resave the .mat file, I was able to load it using the 8GB Ram one.
