Comment (by ajinkya):
should we have corresponding wrapper implementations for all these pca
methods from armadillo ?
mat coeff = princomp(mat X)
cx_mat coeff = princomp(cx_mat X)
princomp(mat coeff, mat X)
princomp(cx_mat coeff, cx_mat X)
princomp(mat coeff, mat score, mat X)
princomp(cx_mat coeff, cx_mat score, cx_mat X)
princomp(mat coeff, mat score, vec latent, mat X)
princomp(cx_mat coeff, cx_mat score, vec latent, cx_mat X)
princomp(mat coeff, mat score, vec latent, vec tsquared, mat X)
princomp(cx_mat coeff, cx_mat score, vec latent, cx_vec tsquared, cx_mat
X)
I am done writing the test case. If we want all the above cases to be
handled, then should the test case test all the apis ??
