# Matrix Processing

PyoObjects to perform operations on PyoMatrixObjects.

PyoMatrixObjects are 2 dimensions table containers. They can be used to store audio samples or algorithmic sequences. Writing and reading are done by giving row and column positions.

## Objects in this category

- `MatrixMorph` : Morphs between multiple PyoMatrixObjects.

- `MatrixPointer` : Matrix reader with control on the 2D pointer position.

- `MatrixRec` : MatrixRec records samples into a previously created NewMatrix.

- `MatrixRecLoop` : MatrixRecLoop records samples in loop into a previously created NewMatrix.

## MatrixMorph

class MatrixMorph(input, matrix, sources)

  Morphs between multiple PyoMatrixObjects.

  Uses an index into a list of PyoMatrixObjects to morph between adjacent matrices in the list. The resulting morphed function is written into the matrix object at the beginning of each buffer size. The matrices in the list and the resulting matrix must be equal in size.

  Parent

    `PyoObject`

  Args
    input: PyoObject

      Morphing index between 0 and 1. 0 is the first matrix in the list and 1 is the last.

    matrix: NewMatrix

      The matrix where to write morphed function.

    sources: list of PyoMatrixObject

      List of matrices to interpolate from.

  Note

  The out() method is bypassed. MatrixMorph returns no signal.

  MatrixMorph has no mul and add attributes.

      >>> s = Server().boot()
      >>> s.start()
      >>> m1 = NewMatrix(256, 256)
      >>> m1.genSineTerrain(1, 4)
      >>> m2 = NewMatrix(256, 256)
      >>> m2.genSineTerrain(2, 8)
      >>> mm = NewMatrix(256, 256)

## MatrixRec

class MatrixRec(input, matrix, fadetime=0, delay=0)

  MatrixRec records samples into a previously created NewMatrix.

  See `NewMatrix` to create an empty matrix.

  The play method is not called at the object creation time. It starts the recording into the matrix, row after row, until the matrix is full. Calling the play method again restarts the recording and overwrites previously recorded samples. The stop method stops the recording. Otherwise, the default behaviour is to record through the end of the matrix.

  Parent

    `PyoObject`

  Args
    input: PyoObject

      Audio signal to write in the matrix.

    matrix: PyoMatrixObject

      The matrix where to write samples.

    fadetime: float, optional

      Fade time at the beginning and the end of the recording in seconds. Defaults to 0.

    delay: int, optional

      Delay time, in samples, before the recording begins. Available at initialization time only. Defaults to 0.

  Note

  The out() method is bypassed. MatrixRec returns no signal.

  MatrixRec has no mul and add attributes.

  MatrixRec will send a trigger signal at the end of the recording. User can retreive the trigger streams by calling obj[‘trig’]. See TableRec documentation for an example.

  out(chnl=0, inc=1, dur=0, delay=0)

    Start processing and send samples to audio output beginning at chnl.

    This method returns self, allowing it to be applied at the object creation.

    Args
      chnl: int, optional

        Physical output assigned to the first audio stream of the object. Defaults to 0.

      inc: int, optional

        Output channel increment value. Defaults to 1.

      dur: float, optional

        Duration, in seconds, of the object’s activation. The default is 0 and means infinite duration.

      delay: float, optional

        Delay, in seconds, before the object’s activation. Defaults to 0.

    If chnl >= 0, successive streams increment the output number by inc and wrap around the global number of channels.

    If chnl is negative, streams begin at 0, increment the output number by inc and wrap around the global number of channels. Then, the list of streams is scrambled.

    If chnl is a list, successive values in the list will be assigned to successive streams.

  setMul(x)

    Replace the mul attribute.

    Args
      x: float or PyoObject

        New mul attribute.

  setAdd(x)

    Replace the add attribute.

    Args
      x: float or PyoObject

        New add attribute.

  setInput(x, fadetime=0.05)

    Replace the input attribute.

    Args
      x: PyoObject

        New signal to process.

      fadetime: float, optional

        Crossfade time between old and new input. Defaults to 0.05.

  setMatrix(x)

    Replace the matrix attribute.

    Args
      x: NewMatrix

        new matrix attribute.

  property input

    PyoObject. Audio signal to record in the matrix.

  property matrix

    PyoMatrixObject. The matrix where to write samples.
