GenCheckSum2Mat

PURPOSE

SYNOPSIS

DESCRIPTION

 Check potential loss of precision during sum of two arrays (same dimensions)
 See the supplementary information for a discussion of loss of precision.
 Returns the sum of the two arrays (ar1+ar2).
 A warning is issued if numerical problems are encountered
 (see GenCheckSumNumPb for more details).
 No check is performed if the global variable noCheckSum is defined
 and equal to true.

 Parameters:
 - ar1: scalar, vector, or matrix
 - ar2: scalar, vector, or matrix (same dimension as ar1)
 - sVar: string describing the variable that is being calculated
 - sCaller: string describing the function in which the calculation is
            performed

 Returns: ar1+ar2
