default constructor
Boolean Mat_cd.almostEqual? ( in Mat_cd that )
Returns true if this matrix is almost the same as another one (using a default precision)
Boolean Mat_cd.almostEqual? ( in Mat_cd that, in Float32 precision )
Returns true if this matrix is almost the same as another one
Mat_cd.appendDesc? ( io String string )
Append a String description of this matrix and its element
values to the io String string
clone method
Integer Mat_cd.cols? ()
Boolean Mat_cd.equal? ( in Mat_cd that )
Returns true if this matrix is the same as another one
Complex_d Mat_cd.get? ( in Integer row, in Integer col )
Return the element value at row and col
Hash for this matrix
Mat_cd Mat_cd.linearInterpolate? ( in Mat_cd that, in Complex_d t )
Linearly interpolates this matrix with another one based on a scalar blend value (0.0 to 1.0)
Mat_cd.resize! ( in Integer rows, in Integer cols )
Resize the matrix to rows and cols dimensions
Integer Mat_cd.rows? ()
Mat_cd.set! ( in Integer row, in Integer col, in Complex_d val )
Set the element value at row and col
Mat_cd.setAll! ( in Complex_d val )
Set all the matrix element values to val
Mat_cd.setDiagonal! ( in Integer size, in Complex_d val )
