convert a matlab file to VI

[ytan]

Hi all,

I would like to convert a mat file to VI. The matlab file can be download from:

http://www.embl.de/ExternalInfo/nedelec/misc/matlab/tiffread27.m.

This matlab file can read a TIFF or STK sequence image file.

I've tried to do this for a while, by importing the file into a MATLAB node, but I have not succeeded yet. Especially, I couldn't understand the below three points:

1) how to input the file name (string? file path?).

2) how to use a sub-function.

3) how to output the image (matrix? vector? string?).

Any feedback/insights would be very welcome

Thanks

You would need to add a line in the Matlab Script Node to actually call the function. You can pass in values using Input and Output nodes by right-clicking on the script node and selecting "Add Input" or "Add Output". You then need to set the datatype of the input/output. There's two examples that ship with LabVIEW that you can take a look at.

Out of curiosity I tried the script in Matlab, and it barfed at all of the sample TIFF files. It kept complaining about not supporting compression formats or PlanarConfiguration.

You may want to try this LabVIEW library.
