matfile_varwrite

Arguments

fd

Real: file descriptor (returned by matfile_open).

name

String: name of the variable to write in the file.

value

Any Scilab type: value of the variable to write in the file.

compressionflag

Boolean: indicate if data compression has to be used (flag equaled to %T) or not.

status

Boolean: %T if writing succeeds, %F otherwise.

Description

Writes a variable in a Matlab binary MAT-file opened by matfile_open.

matfile_varwrite will fail if the MAT-file is not open with the "w" mode and will override any variable stored in the file.

Examples

fd = matfile_open("test_matfile.mat","w");
matfile_varwrite(fd, "foo", "bar", %t);
matfile_close(fd);

fd = matfile_open("test_matfile.mat");
matfile_listvar(fd)
matfile_close(fd);
