Description

The operator write_matrixwrite_matrixWriteMatrixWriteMatrixWriteMatrixwrite_matrix writes a matrix to the file FileNameFileNameFileNameFileNamefileNamefile_name. The matrix can be read with read_matrixread_matrixReadMatrixReadMatrixReadMatrixread_matrix. The default HALCON file extension for the matrix is 'mtx'. The format of the file can be selected via the parameter FileFormatFileFormatFileFormatFileFormatfileFormatfile_format. The following values are supported: 'binary'"binary""binary""binary""binary""binary" for a binary file format, and 'ascii'"ascii""ascii""ascii""ascii""ascii" for a ascii text format. In the text format each row of the file contains one row of the matrix. The columns are separated with white spaces. The advantage of using the binary file format instead of the ascii text format is a smaller size of the output file.

Execution Information

Parameters

MatrixIDMatrixIDMatrixIDMatrixIDmatrixIDmatrix_id (input_control)  matrix → HMatrix, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Matrix handle of the input matrix.

Format of the file.

Default value: 'binary' "binary" "binary" "binary" "binary" "binary"

List of values: 'ascii'"ascii""ascii""ascii""ascii""ascii", 'binary'"binary""binary""binary""binary""binary"

FileNameFileNameFileNameFileNamefileNamefile_name (input_control)  filename.write → HTuplestrHTupleHtuple (string) (string) (HString) (char*)

File name.

File extension: .mtx

Result

If the file name is valid (write permission), the operator write_matrixwrite_matrixWriteMatrixWriteMatrixWriteMatrixwrite_matrix returns the value TRUE. If necessary an exception is raised.
