Create a MPSMatrixDescriptor with the specified dimensions and data type. For performance considerations the optimal row stride may not necessarily be equal to the number of columns in the matrix. The MPSMatrix class provides a method which may be used to determine this value, see the rowBytesForColumns API in the MPSMatrix class. The number of matrices described is initialized to 1.

Parameters:

rows - The number of rows of the matrix.

columns - The number of columns of the matrix.

rowBytes - The number of bytes between starting elements of consecutive rows. Must be a multiple of the element size.

dataType - The type of the data to be stored in the matrix.

rowBytesFromColumnsDataType

public static long rowBytesFromColumnsDataType(long columns,
                                               int dataType)

Return the recommended row stride, in bytes, for a given number of columns. To achieve best performance the optimal stride between rows of a matrix is not necessarily equivalent to the number of columns. This method returns the row stride, in bytes, which gives best performance for a given number of columns. Using this row stride to construct your array is recommended, but not required (provided that the stride used is still large enough to allocate a full row of data).

Parameters:

columns - The number of columns in the matrix for which the recommended row stride, in bytes, is to be determined.

dataType - The type of matrix data values.

Create a MPSMatrixDescriptor with the specified dimensions and data type. For performance considerations the optimal row stride may not necessarily be equal to the number of columns in the matrix. The MPSMatrix class provides a method which may be used to determine this value, see the rowBytesForColumns API in the MPSMatrix class.

Parameters:

rows - The number of rows of a single matrix.

columns - The number of columns of a single matrix.

matrices - The number of matrices in the MPSMatrix object.

rowBytes - The number of bytes between starting elements of consecutive rows. Must be a multiple of the element size.

matrixBytes - The number of bytes between starting elements of consecutive matrices. Must be a multiple of rowBytes.

dataType - The type of the data to be stored in the matrix.
