DataSet Construction

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.

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. This can be shown by creating an array of random numbers.

>> >> randomdata = rand(20,15);
>> data = dataset(randomdata)
 
data = 
       name: randomdata
       type: data 
       date: 23-May-2016 11:18:14
       data: 20x15 [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  [: 1x20] 
               Mode 2  [: 1x15]
