</span><br><span class=help> <span class=help_field>Description:</span></span><br><span class=help> createdata or createdata('finite') invokes an interactive generator
</span><br><span class=help> of finite point sets in 2D. The generated points can be assigned
</span><br><span class=help> into two classes (1,2). The generator saves data to a
</span><br><span class=help> specified file. The file has the following fields:
</span><br><span class=help> X [2 x num_data] 2D vectors.
</span><br><span class=help> y [1 x num_data] Assigned labels.
</span><br><span class=help>
</span><br><span class=help> createdata('finite',num_classes) when num_classes is specified
</span><br><span class=help> then the points can be assigned labels from 1 to num_classes.
</span><br><span class=help>
</span><br><span class=help> createdata('gauss') invokes an interactive generator of
</span><br><span class=help> Gaussian distributions. A user can specify mean vector and
</span><br><span class=help> covariance matrix. The generator saves data to a file
</span><br><span class=help> having the following fields:
</span><br><span class=help> Mean [2 x ncomp] Mean vectors.
</span><br><span class=help> Cov [2 x 2 x ncomp] Covariance matrices.
</span><br><span class=help> y [1 x ncomp] Assigned labels.
</span><br><span class=help>
</span><br><span class=help> createdata('gauss',num_classes) when num_classes is specified
</span><br><span class=help> then the distributions can be assigned labels from 1 to num_classes.
</span><br><span class=help>
</span><br><span class=help> The data generator is controlled by mouse:
</span><br><span class=help> Left button ... creates a new point or Gaussian.
</span><br><span class=help> Right button ... erases the focused point or Gaussian.
</span><br><span class=help>
</span><br><span class=help> In the case of generating Gaussians left button double-click makes
</span><br><span class=help> selected Gaussian focused. The covariance matrix of focused
</span><br><span class=help> Gaussian can be modified.
