The cell array is a Matlab container for the storage of series of objects in the memory workspace. Individuals elements are accessed or created with the curly bracket {} notation. Cell arrays are available both in Matlab and in the standalone versions of Dynamo.
Contents
Basic syntax
Some basic examples:
a = {};
creates an empty cell array called a in the memory workspace.
a = {'hello','bye'};
creates a cell array that contains the strings hello and bye, so that
disp(a{1}); will just write the string hello in the Matlab desktop ( or in the Dynamo standalone console).
Individual elements can be added through the {}notation:
a{3} = 'hi again';
will enlarge the cell array with a third element.
A complete (and rather lengthy) description can be found in the |matlab page
Cell arrays in Dynamo
Cell arrays are frequently of interest for Dynamo users that need to perform operations that are complicated or not available through the GUIs.
Loops on models
Extracting model files from a catalogue
The names of the model files in a catalogue can be easily extracted with the command line dcm utility. In the command:
dcm myCatalogue -i * -l m -ws o
the flags have the meaning:
- -i *
- -i *
- -ws o
so that the order will show on screen the names of all the models inside the catalogue myCatalogue.
