clatlab

clatlab is a bridge between Matlab and clij2.

Installation

Download the following files, removed the numbers from their file endings and put them all in the `/Documents/MATLAB folder:

Test the installation by executing this script from matlab:

clij2 = init_clatlab();
% print out name of used GPU:
clij2.getGPUName()

Example code

Examples are available in the matlab folder.

Clatlab provides two entry points for processing:

clij2.gaussianBlur(imageIn, imageOut, 5, 5);
Command Matlab expresson clij2 counter part  
push(a)   c = clij2.pushMat(a);  
pull(a)   c = clij2.pullMat(a);

How to develop clatlab

Clone this repository and build it using maven. Afterwards, you find the clatlab.jar in the target directory. Copy it to your clatlab/matlab java classpath.

git clone https://github.com/clij/clatlab
cd clatlab
mvn package
cp target/clatlab*.jar classpath/
