Abstract

A program is disclosed that analyzes location errors in circuit boards or in any device with a similar two-dimensional pattern. The analysis does not require the usual technique of inversion of a rectangular matrix. It is consequently well adapted to small computers and can be effectively employed in remote locations where large "main-frame" systems are not available for matrix inversion.

Parameter Calculation Program

      A program is disclosed that analyzes location errors in
circuit boards or in any device with a similar two-dimensional
pattern.  The analysis does not require the usual technique of
inversion of a rectangular matrix.  It is consequently well adapted
to small computers and can be effectively employed in remote
locations where large "main-frame" systems are not available for
matrix inversion.

      Execution is by algebraic substitution into the formulas
defined in Fig. 1.  Operation of the program is described by the flow
diagram shown in Fig. 2.
