As an example, if you have a yml file
like this one, that I'll call demo.yml
Then, you can use OpenCV FileStorage class to load the variables contained on this demo.yml file
as:

%YAML:1.0 Variable1: !!opencv-matrix rows: 4 cols: 5 dt: f data: [ -1.60522782e-03, -5.93489595e-03, 2.92204670e-03, 1.14785777e-02, -1.57432575e-02, -2.17529312e-02, 4.05947529e-02, 6.56594411e-02, 1.24527821e-02, 3.19751091e-02, 5.41692637e-02, 4.04683389e-02, 2.59191263e-03, 1.15112308e-03, 1.11024221e-02, 4.03668173e-03, -3.19138430e-02, -9.40114353e-03, 4.93452176e-02, 5.73473945e-02 ] Variable2: !!opencv-matrix rows: 7 cols: 2 dt: f data: [ -2.17529312e-02, 4.05947529e-02, 5.73473945e-02, 6.56594411e-02, 1.24527821e-02, 3.19751091e-02, 5.41692637e-02, 4.03668173e-03, -3.19138430e-02, -9.40114353e-03, 4.93452176e-02, 4.04683389e-02, 2.59191263e-03, 1.15112308e-03 ]
