Parameters

tolerance: Type: System Double
The tolerance to use against each matrix element.

Return Value

Type: Boolean

True if the matrix is an identity matrix within the specified tolerance; False if it is not.

Remarks

Returns true if:

MatrixElement(0, 0) = 1 +/- toleranceMatrixElement(0, 1) = 0 +/- toleranceMatrixElement(1, 0) = 0 +/- toleranceMatrixElement(1, 1) = 1 +/- tolerance
