Constructor Details

AbsMatrix

public AbsMatrix(MQ matrix,
 Reference<?,A,Q> reference)

Create a new matrix of absolute values with a reference point.

Parameters:

matrix - the underlying relative matrix with SI values relative to the reference point

reference - the reference point for the absolute values

Method Details

format

public String format()

Concise description of this matrix.

Returns:

a String with the matrix, with the unit attached.

format

public String format(MatrixFormat format)

String representation of this matrix after applying the format.

Parameters:

format - the format to apply for the matrix

Returns:

a String representation of this matrix, formatted according to the given format

format

public String format(Unit<?,Q> targetUnit)

String representation of this matrix, expressed in the specified unit.

Parameters:

targetUnit - the unit into which the values of the matrix are converted for display

Returns:

printable string with the matrix's values expressed in the specified unit
