Arguments
- filename
String: the path of the file. Must contain only ANSI character.
- mode
String: file access type (
"r"
by default)."r": opens the file for reading.
"w": creates an empty file or opens it for writing.
- version
Scalar string: file version format (
"5"
by default)."5": Matlab 5 file.
"7.3": Matlab 7.3 file.
- fd
Real: file descriptor (-1 if opening failed).
Description
Opens a Matlab binary MAT-file for reading or writing data.
If mode is set to w , the content of filename will be reseted. |
Examples
A = rand(10, 10); B = sprand(100, 100, 0.1); savematfile("test_matfile.mat", "A", "B", "-v6"); clear(); fd = matfile_open("test_matfile.mat"); matfile_listvar(fd) matfile_close(fd); //fd = matfile_open("test_matfile.mat", "w"); // Empty test_matfile.mat //fd = matfile_open("test_matfile.mat", "w", "7.3"); // Empty test_matfile.mat as a Matlab 7.3 file
