Garbage values when storing the data into .dat file

Hello there, I have a 3D array having data type float. When i store this array into a .txt or .mat file and then open it, it has only random data.

I am using the following command: save('test.txt','x'); Can someone help me?

What you see is the expected output: The 3D array is writting in binary format to the MAT file. It is not random and after a load() you get back the original data.

What exactly is your question? Do you want to create a text file, which can be read by humen? If so, are you really sure, that you need this? A 3D-array need some reshaping to a 2D-matrix for awriting it to a file. Then the values and the structure is not clear anymore in every case. Therefore I'd suggest to stay at the binary format and use Matlab as a viewer of the data, not Notepad.

Hi thanks for reply. It throws me following error:

Sorry, I overlooked that it is 3D. There is no standard text representation for 3D arrays.

It would be possible to write the array to a .m file as code that would recreate the 3D array. For example it could build all the slides and cat(3) them together.
