load

Load a saved variable or a serie of variables

Calling Sequence

load(filename [,x1,...,xn])

load(fd [,x1,...,xn])

Arguments

:filename character string containing the path of the file : :fd a file descriptor given by a call to mopen : :xi arbitrary Scilab variable name(s) given as strings. :

Description

The load command can be used to reload in the Scilab session variables previously saved in a file with the ``save`_` command. If the file contains graphic handle variables, the corresponding graphics_entities are drawn.

load(filename) loads the variables saved in file given by its path filename.

load(fd) loads the variables saved in file given by its descriptor fd. This prototype is obsolete and will be removed in Scilab 6.

load(filename,’x’,’y’) loads only variables x,y.

load(fd,’x’,’y’) loads only variables x,y. This prototype is obsolete and will be removed in Scilab 6..

The change of format between the family 5 and 6 of Scilab has been decided because the 5 format is undocumented, not specified and hard to read. SOD (Scilab 6 default format) is fully documented and easy to read through HDF5 libraries or applications.

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

Examples

// Binary format readable up to Scilab 5 family
a=`eye`_(2,2);b=`ones`_(a);
`save`_('vals.dat',a,b);
clear a
clear b
load('vals.dat','a','b');

// Binary format readable by Scilab 5.4.X and Scilab 6 family
a=`eye`_(2,2);b=`ones`_(a);
`save`_("val.sod", "a", "b");
clear a
clear b
load("val.sod", "a", "b");

History

Version Description 5.0.0 All uimenu or uicontrol handles are also loaded by this function. 5.4.0

• The load function is able to handle both Scilab 5 and SOD (Scilab 6 format) by default.
• The Scilab 5.X format is deprecated and will be removed with Scilab 6.
• Using load with a file descriptor as first input argument is deprecated and will be removed with Scilab 6.
