I have uploaded a paper in which there is the description of the alternating projections method. I want to write R code for applying this method in order to compute the nearest correlation matrix when a symmetric matrix is given(see paper for details). In my case I dont want to use directly the "nearPD" function from R but I want to write my own simpler code without using so many constraints as the above function. I want just to project to sets S and U and to use the Dykstra correction(see paper). Finally,I want to test the code to a simple real data set(for example a 8x8 matrix of stocks). Please follow code instructions carefully.
