matfile_varwrite
Write a variable in a Matlab binary MAT-file.
Syntax
status = matfile_varwrite(fd, name, value, compressionflag)
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);
