Image Acquisition Toolbox

save

Save image acquisition objects to a MAT-file

Syntax

• save filename
  save filename obj1 obj2 ...
  save('filename','obj1','obj2',...)
  

Description

save filename saves all variables in the MATLAB workspace to the MAT-file filename. If filename does not include a file extension, save appends the .MAT extension to the filename.

save filename obj1 obj2 ... saves the specified image acquisition objects (obj1, obj2, etc.) to the MAT-file filename.

save('filename','obj1','obj2',...) is the functional form of the command, where the file name and image acquisition objects must be specified as strings. If no objects are specified, then all variables existing in the MATLAB workspace are saved.

Note    Any data associated with the image acquisition object is not stored in the MAT-file. To save the data, bring it into the MATLAB workspace (using the getdata function), and then save the variable to the MAT-file.

To return variables from the MAT-file to the MATLAB workspace, use the load command. Values for read-only properties are restored to their default values upon loading. For example, the Running property is restored to 'off'. Use the propinfo function to determine if a property is read only.

Examples

• obj = videoinput('winvideo', 1);
  set(obj, 'SelectedSourceName', 'input1')
  save fname obj
  set(obj, 'TriggerFcn', {'mycallback', 5});
  save('fname1', 'obj')
