coeff = gsp_pyramid_cell2coeff(ca,pe);
| ca | Cell array with the coarse approximation at each level |
| pe | Cell array with the prediction errors at each level |
| coeff | Vector of coefficient |
This function compress the cell array ca and pe into a single vector of coefficients. It keeps the smaller coarse approximation and the prediction errors.
Example:
[ca,pe] = gsp_pyramid_analysis(Gs, f); coeff = gsp_pyramid_cell2coeff(ca,pe);
