Can we use known frequencies in these kind of fittings?


You made my work with this package many times easier because I hadn't to write all these hsvd functions by myself just from theoretical papers :D

AWESOME package


To fix the issue commented out in the function lpsvd(y,fs)

replace the line:
b = b + (1/s(1))*(uk'*h)*V(:,k);
b = b + (1/s(k))*(uk'*h)*V(:,k);
