save

Arguments

filename

Character string containing the path of the file

fd

A file descriptor given by a call to mopen

xi

Arbitrary Scilab variable(s)

Description

The save command can be used to save Scilab current variables in a binary file. If a variable is a graphic handle, the save function saves all the corresponding graphics_entities definition.

Since Scilab 5.0, all uimenu or uicontrol handles are also saved by this function.

The file can be given either by its paths or by its descriptor previously given by mopen.

save(filename) saves all current variables in the file defined by filename.

save(fd) saves all current variables in the file defined by the descriptor fd.

save(filename,x,y) or save(fd,x,y) saves only named variables x and y.

Saved variables can be reloaded by the load command.

Note that the written file is portable to other operating systems and architectures (little and big endian).

Examples

a=eye(2,2);b=ones(a);
save('val.dat',a,b);
clear a
clear b
load('val.dat','a','b');

// sequential save into a file
fd=mopen('TMPDIR/foo','wb')
for k=1:4, x=k^2;save(fd,x,k),end
mclose(fd)
fd=mopen('TMPDIR/foo','rb')
for i=1:4, load(fd,'x','k');x,k,end
mclose(fd)

// appending variables to an old save file
fd=mopen('TMPDIR/foo','r+')
mseek(0,fd,'end') 
lst=list(1,2,3)
save(fd,lst)
mclose(fd)
