`apt`¶

Approximate Pake transformation (APT) of dipolar spectroscopy data

Warning

This is a legacy function. Its use is not recommended for routine or accurate data analysis.

Syntax¶

P = apt(S,K)
P = apt(S,K,DDS)
[P,r] = apt(S,K,DDS)

Parameters

S - Time-domain data (N-element array)
K - APT kernel components (struct)
d - Distance-domain smoothing parameter (scalar);

Returns

P - Distance distribution (M-element array)
r - Distance axis (M-element array)

Description¶

[P,r] = apt(S,K)

Computes the distance distribution P and distance axis r from the time-domain signal S using the APT kernel K, which must be a structure as generated by the aptkernel function.

[P,r] = apt(S,K,DDS)

The distance-domain smoothing parameter (DDS) can be specified by passing it as scalar value DDS. If not specified, a default value of 0.05 is selected.

The APT results are allowed to adopt negative values since no negativity constraint is imposed upon them. Additionally, the output distribution is not normalized.
