| ==Getting Started==
| |
| In general, data is stored in a dataset object.
| |
|
| |
|
|
| |
|
| |
|
| |
|
| |
| ==From a GUI==
| |
|
| |
| Using PLS_Toolbox and Solo, it is easy to import data into a dataset object using the data importer. From the workspace browser select File/Import Data to launch the GUI.
| |
|
| |
|
| |
| Alternatively this can be acheived by dragging the desired file into the Workspace Browser. In the case of text based file formats such as CSV, this will launch the following window.

|
| |
| ==From the MATLAB Command Line==
| |
|
| |
|
| |
| From the command line, the easiest way to create a dataset is to pass an array to the dataset function. First we will create an array of data to be passed to the dataset function.
| |
|
| |
| <pre>
| |
| >> t = [0:0.1:10]';
| |
| >> x = [cos(t) sin(t) exp(-t)];
| |
| >> data = dataset(x)
| |
|
| |
| data =
| |
| name: x
| |
| type: data
| |
| date: 23-May-2016 11:24:53
| |
| moddate: 23-May-2016 11:24:53
| |
| data: 101x3 [double]
| |
| label: {2x1} [array (char)]
| |
| Mode 1 [: ]
| |
| Mode 2 [: ]
| |
| axisscale: {2x1} [vector (real)] (axistype)
| |
| Mode 1 [: ] (none)
| |
| Mode 2 [: ] (none)
| |
| title: {2x1} [vector (char)]
| |
| Mode 1 [: ]
| |
| Mode 2 [: ]
| |
| class: {2x1} [vector (double)]
| |
| Mode 1 [: ]
| |
| Mode 2 [: ]
| |
| classid: {2x1} [cell of strings]
| |
| include: {2x1} [vector (integer)]
| |
| Mode 1 [: 1x101]
| |
| Mode 2 [: 1x3]
| |
| history: {1x1 cell} [array (char)]
| |
| OTHER: [View Class Summary]
| |
| </pre>
| |
|
| |
| Alternatively we could start with an empty dataset and assign the the array x to its data field.
| |
|
| |
| <pre>
| |
| newdata = dataset;
| |
| newdata.data = x;
| |
| </pre>
| |
|
| |
| Similarly we may set the other fields of the dataset object individually.
| |
|
| |
| <pre>
| |
| vars = {'cos(t)';'sin(t)';'exp(-t)'};
| |
| newdata.author = 'Data Manager'; %sets the author field
| |
| newdata.label{2} = vars; %sets the labels for columns = dimension 2
| |
| newdata.labelname{2} = 'Variables'; %sets the name of the label for columns
| |
| newdata.axisscale{1} = t; %sets the axis scale for rows = dimension 1
| |
| newdata.axisscalename{1} = 'Time'; %sets the name of the axis scale for rows
| |
| newdata.title{1} = 'Time (s)'; %sets the title for rows
| |
| newdata.titlename{1} = 'Time Axis'; %sets the titlename for rows
| |
| newdata.title{2} = 'f(t)'; %sets the title for columns
| |
| newdata.titlename{2} = 'Functions'; %sets the titlename for columns
| |
| </pre>
| |
|
| |
| ==Creating 3-Way Data==
| |
|
| |
| Perhaps the easiest way to import 3-way data is to use the import data GUI.
