Abstract
A matrix method for relating the field ratios to the voltage sources is presented. As a moment-method program is running, the field and base current for each tower is recorded. Matrices that relate base currents to field ratios, can be extracted from this data or by inverting a matrix. This method is an exact solution and requires only one run of the moment-method program. For this reason, it is superior to other iterative processes
