17 -- Function File: NB = dxfwrite (FILENAME, PL, ...)
18 Write FILENAME as a DXF file. Polyline PL must be defined as
19 matrix of 1, 2 or 3 columns respectively for x, y and z
20 coordinates. The number of polyline (NB) or 0 is returned.

44 -- Function File: gplot3 (A, XYZ)
45 -- Function File: gplot3 (A, XYZ, LINE_STYLE)
46 -- Function File: [X, Y, Z] = gplot3 (A, XYZ)
47 Plot a 3-dimensional graph defined by A and XYZ in the graph
48 theory sense. A is the adjacency matrix of the array to be
49 plotted and XY is an N-by-3 matrix containing the coordinates of
50 the nodes of the graph.
52 The optional parameter LINE_STYLE defines the output style for the
53 plot. Called with no output arguments the graph is plotted
54 directly. Otherwise, return the coordinates of the plot in X and

83 -- Function File: [COUNTS, XBINS, YBINS] = hist2d ([X, Y], XBINS,
85 Produce a 2D histogram.
87 Points xi,yi are stored in a 2-column array. If ybins is missing,
88 use xbins. If bins is a scalar, use that many bins. If bins is a
89 vector, it represents bin edges.

116 -- Function File: plotdecimate (P, SO, RES)
117 Optimise plot data by removing redundant points and segments
119 The first parameter P is a two-column matrix to be plotted as X and
120 Y coordinates. The second optional argument SO disables segment
121 optimisation when set to FALSE (default is TRUE). The third
122 optional argument RES is the size of the largest error on the plot:
123 if it is a scalar, it is meant relative to the range of X and Y
124 values (default 1e-3); if it is a 2x1 array, it contains the
125 absolute errors for X and Y. Returns a two-column matrix
126 containing a subset of the rows of P. A line plot of P has the
127 same appearance as a line plot of the output, with errors smaller
128 than RES. When creating point plots, set SO to FALSE.

153 -- Function File: tics (AXIS, [POS1, POS2, ...], [LAB1, LAB2, ...],)
154 Explicitly set the tic positions and labels for the given axis.
156 AXIS must be 'x', 'y' or 'z'.
158 If no positions or labels are given, then restore the default. If
159 positions are given but no labels, use those positions with the
160 normal labels. If positions and labels are given, each position
161 labeled with the corresponding row from the label matrix.

186 -- Function File: tricontour (TRI, X, Y, Z, LEVELS)
187 -- Function File: tricontour (TRI, X, Y, Z, LEVELS, LINESPEC)
188 Plot level curves for the values of `Z' on a triangular mesh in 2D.
190 The variable TRI is the triangular meshing of the points `(X, Y)'
191 which is returned from `delaunay'. The variable LEVELS is a vector
192 with the values of the countour levels. If LEVELS is a scalar,
193 then it corresponds to the number of level curves to be drawn. If
194 exactly one level curve is desired, list the level twice in the
197 If given, LINESPEC determines the properties to use for the lines.
199 The output argument H is the graphic handle to the plot.
