save - saving variables in binary files

Calling Sequence

save(filename [,x1,x2,...,xn])

save(fd [,x1,x2,...,xn])

Parameters

• 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. 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.

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)
