Compile as library: fl-build kernel_pca Compile executable from library kernel_matrix_algs fl-build kernel_pca_main_from_lib Compile executable from scratch (without using library) fl-build kernel_pca_main_standalone If you look at the bash shell script 'do_kernel_pca', you will see an example of using fx-run to run an experiment with multiple bandwidths. Alternatively, you can just run the program without using fx-run, for a single set of parameters: ./kernel_pca_main_standalone --data=data.txt --algs/h=0.5
