Re: Multibandread in octave

[Cameron MacArthur]

Thank you so much Mr. Ohlhus! That's all very helpful.  I think I'll be able to do it now.  Can't thank you enough!

Sincerely,

Cam

Hello Cam,

I think you refer to this MATLAB-function: http://www.mathworks.de/de/help/matlab/ref/multibandread.html

This function isn't implemented by Octave or any Octave-forge package as far as I can say. I don't know what your colleague did with this function, it seems to be a convenience wrapper for simple C-style binary I/O. If you are familiar with the C programming language, it would be no problem to get you binary I/O done by reading this section of the GNU/Octave manual: https://www.gnu.org/software/octave/doc/interpreter/C_002dStyle-I_002fO-Functions.html

Many parameters of multibandread() that seem important to me for binary I/O can be found in other functions:

- Open binary file with certain byte order https://www.gnu.org/software/octave/doc/interpreter/Opening-and-Closing-Files.html#Opening-and-Closing-Files

- Read raw binary data with a given precision https://www.gnu.org/software/octave/doc/interpreter/Binary-I_002fO.html#Binary-I_002fO

Only the interleaving (the repetition of certain data structures) must be controlled by you with for example for-loops.

Good luck with your project,

Kai

Hello all,

I noticed via Octave Forge, that there is a missing-functions package for Octave in an effort to eventually have it include all matlab functions. I am desperately trying to do with Octave what a colleague did with matlab and the multibandread function. Is there any function like multibandread in Octave?  And if not, do you know of any other way (ie 3rd party app) I can do multibandread? I figured you all would be the right people to ask.  Hopefully you can help me!

Thanks much,

-Cam
