Two dimensional sparse canonical correlation analysis (Sparse2DCCA) for blind source separation and brain image analysis.

Sparse2DCCA

Usage: Just run demo.m file in MATLAB. I have used MATLAB 2017b version to successfully run these scripts.

In case you come across any issue running this simulation setup, please file an issue. I will try to respond as soon as possible.

Undefined function in Sparse_2DCCA_rank1

there is an undefined function in Sparse_2DCCA_rank1， line 90, "Lxt = OMP_1D(Kxy*yLy,Xr',reg_wx);". Could you please give the code of this function or give some explanation so I can rewrite it. Thank you so much!
