# METHODS

Class methods are listed below. Inherited methods are not included.

## COUNT Returns the number of occurrences of a pattern in text.

C = COUNT(STR,PATTERN) returns the number of occurrences of PATTERN in STR.

STR can be a string array, a character vector, or a cell array of character vectors. So can PATTERN. PATTERN and STR need not be the same size. If PATTERN is a string array or a cell array, then COUNT returns the total number of occurrences of all elements of PATTERN in STR.

C = COUNT(STR,PATTERN,'IgnoreCase',IGNORE) ignores case when searching for PATTERN in STR if IGNORE is true. The default value of IGNORE is false.

Examples STR = "data.tar.gz"; P = "tar"; COUNT(STR,P) returns 1

STR = ["abstracts.docx","data.tar.gz"]; P = 'tar'; COUNT(STR,P) returns [0 1]

STR = "data.tar.gz"; P = {'docx','tar'}; COUNT(STR,P) returns 1

STR = {'DATA.TAR.GZ','SUMMARY.PPT'}; P = "tar"; COUNT(STR,P,'IgnoreCase',true) returns [1 0]

## this.find(*arguments*) Find OctTreeNode containing given point.

## OctTree/this.find_closest_local(*arguments*) is a function.

[x_local, elements] = **find_closest_local**(*this*, X)

## OctTree.this.from_mesh(*arguments*) is a function.

*this* = **from_mesh**(m3d, varargin)

## OctTree.this.from_parent(*arguments*) is a function.

*this* = **from_parent**(parent, elements, xmin, xmax, ymin, ymax, zmin, zmax)

## OctTree/this.get_root(*arguments*) is a function.

p = **get_root**(*this*)

## PLOT Linear plot.

PLOT(X,Y) *plot*s vector Y versus vector X. If X or Y is a matrix, then the vector is *plot*ted versus the rows or columns of the matrix, whichever line up. If X is a scalar and Y is a vector, disconnected line objects are created and *plot*ted as discrete points vertically at X.

PLOT(Y) *plot*s the columns of Y versus their index. If Y is complex, PLOT(Y) is equivalent to PLOT(real(Y),imag(Y)). In all other uses of PLOT, the imaginary part is ignored.

Various line types, **plot** symbols and colors may be obtained with PLOT(X,Y,S) where S is a character string made from one element from any or all the following 3 columns:

b blue . point - solid g green o circle : dotted r red x x-mark -. dashdot c cyan + plus -- dashed m magenta * star (none) no line y yellow s square k black d diamond w white v triangle (down) ^ triangle (up) < triangle (left) > triangle (right) p pentagram h hexagram

For example, PLOT(X,Y,'c+:') *plot*s a cyan dotted line with a plus at each data point; PLOT(X,Y,'bd') *plot*s blue diamond at each data point but does not draw any line.

PLOT(X1,Y1,S1,X2,Y2,S2,X3,Y3,S3,...) combines the *plot*s defined by the (X,Y,S) triples, where the X's and Y's are vectors or matrices and the S's are strings.

For example, PLOT(X,Y,'y-',X,Y,'go') *plot*s the data twice, with a solid yellow line interpolating green circles at the data points.

The PLOT command, if no color is specified, makes automatic use of the colors specified by the axes ColorOrder property. By default, PLOT cycles through the colors in the ColorOrder property. For monochrome systems, PLOT cycles over the axes LineStyleOrder property.

Note that RGB colors in the ColorOrder property may differ from similarly-named colors in the (X,Y,S) triples. For example, the second axes ColorOrder property is medium green with RGB [0 .5 0], while PLOT(X,Y,'g') *plot*s a green line with RGB [0 1 0].

If you do not specify a marker type, PLOT uses no marker. If you do not specify a line style, PLOT uses a solid line.

PLOT(AX,...) *plot*s into the axes with handle AX.

PLOT returns a column vector of handles to lineseries objects, one handle per *plot*ted line.

The X,Y pairs, or X,Y,S triples, can be followed by parameter/value pairs to specify additional properties of the lines. For example, PLOT(X,Y,'LineWidth',2,'Color',[.6 0 0]) will create a **plot** with a dark red line width of 2 points.

Example x = -pi:pi/10:pi; y = tan(sin(x)) - sin(tan(x)); **plot**(x,y,'--rs','LineWidth',2,... 'MarkerEdgeColor','k',... 'MarkerFaceColor','g',... 'MarkerSize',10)
