1. An information processing apparatus comprising
a processing circuit configured to acquire a measurement field corresponding to a spatial distribution of a predetermined physical quantity in a subject of measurement, and calculate an unknown quantity in the subject of measurement based on a first equation between the measurement field and the unknown quantity having spatial dependence, and on the acquired measurement field, wherein
the first equation is one that is acquired based on a second equation expressing a dual field divergence of which is capable of being expressed using the measurement field by using the measurement field and the unknown quantity, and on the Helmholtz decomposition of the dual field.
